$v.latestStateEn doi: 10.11883/bzycj-2020-0020 Read OL PDF (1) Abstract: The calculation method based on the energy method for resisting perforation to the SC walls with tied bars was discussed. Based on the perforation mechanism of missile impacting on the SC walls, the dissipated energy was divided into four parts: the energy dissipated by the front and rear steel plates, the energy dissipated by internal concrete and tied bars, and a practical calculation formula of preventing perforation was proposed. The perforation velocity and the residual velocity of the SC walls with tied bars can be calculated by the practical calculation formula when the related parameters of the materials and geometry about the missile and SC walls are known, thus avoiding complex impacting numerical analysis of dynamic time history. In order to verify the reliability of the formula, the results calculated through the practical formula were compared with the existing test data, as well as the dynamic finite element (FE) analysis results. The perforation state of the SC walls can be judged by the practical calculation formula concretely, and the residual velocities of the missile given by the formula are in good agreement with the test results. To further verify the application extent of the formula, the FE models about 10 cases of an aircraft engine impacting on the SC walls were established, and the solid FE models and the front closed cylindrical shell FE models of the aircraft engine were described, respectively. The results calculated through the practical formula were compared with the 10 cases of the aircraft engine impacting on the SC wall. It indicates that the deviation value of one case is slightly more than 10%. In other cases, the deviation values are all less than 10%. The accuracy and effectiveness of the proposed method can be verified.$v.latestStateEn  doi: 10.1183/bzycj-2019-0481
Abstract:
The impact of nozzle configuration on the performance of rotating detonation with different equivalence ratios was studied through tests on rotating detonating engines (RDEs) without a nozzle and with a convergent nozzle, a divergent nozzle and a convergent-divergent nozzle, respectively. Pre-combustion cracked kerosene and 30% oxygen-enriched air were used as the fuel and oxidizer, respectively. The results show that the rotating detonation engines can operate smoothly with the equivalence ratio ranging from 0.73 to 1.3. Three operating modes including single wave, unstable two counter-rotating waves and stable two counter-rotating waves were found in the experiments. The nozzle configurations strongly affect the mode transition and the detonation wave velocity. The convergent nozzle and the convergent-divergent nozzle can promote the generation of new detonation waves, making the working modes mainly to be two counter-rotating waves, while the detonation mainly operates in the single wave mode with a divergent nozzle installed. The results further show that the maximum propagating velocity deviates from the stoichiometric ratio when the convergent or convergent-divergent nozzles are installed, and the convergent-divergent nozzle can increase the detonation wave velocity.
$v.latestStateEn doi: 10.11883/bzycj-2019-0479 Read OL PDF (0) Abstract: Due to the excavation unloading effect and the amplitude attenuation of stress wave, the rock mass locating the different distances away from the blasting source are subjected to different geostress and impact loadings during the blasting excavation of underground rock mass. The construction of relationship between rock dynamic failure properties with impact loadings has more important engineering practical significance compared with representating them with strain rate. In order to investigate the effect of the values of impact loading and the geostress on the characteristics of rock failure and energy dissipation, impact experiments of red sandstone were carried out with a modified split Hopkinson pressure bar testing system, the impact velocities and axial static stresses were set seven levels, respectively. The effects of impact velocity on the failure model and mechanism of red sandstone under different axial static stresses were researched based on the broken rock specimens. By analyzing the energy values of stress waves under different experimental conditions, the effects of the impact velocity and the axial static stress on energy dissipation of red sandstone were investigated. The fragment fractal dimension of red sandstone under different impact velocities and axial static stresses were studied based on the sieve test results of the broken specimens. The results show that the increase of impact velocity will aggravate the destroy degree of the red sandstone. The main part after macroscopic failure remains a circular cylinder when a specimen is subjected to impact loading and no axial static stress, the failure of the specimen is resulted from its insufficiency of resistance to tensile deformation; but the main part after macroscopic failure represents a hourglass shape when the specimen is under coupled axial static stress and impact loading, the failure mechanism is mixed tension and shear fracture. The dissipation energy of the red sandstone increases in a quadratic function with increasing the impact velocity, the higher the axial static stress, the smaller the increasing amplitude. With the increase of impact velocity, the fractal dimension of the red sandstone increases from zero gradually. For a rock specimen subjected to specific axial static stress, there is a critical impact velocity which signifies that the fractal dimension of the specimen will change from zero to greater than zero, and the critical impact velocity increases first and then decreases with the increase of axial static stress.$v.latestStateEn  doi: 10.11883/bzycj-2019-0478
Abstract:
To investigate the influence of water depth on the evolution characteristics of the muzzle flow field of underwater submerged launched ballistic gun, a two-dimensional axisymmetric transient muzzle flow field model was established. The fluid volume function multiphase flow model, standard k-ε turbulence model, Schnerr-Sauer cavitation model, combined with dynamic grid and user-defined function technology, are used to numerically simulate the evolution process of underwater muzzle flow field. An underwater visualized shooting experimental platform for a ballistic gun was built. The evolution process of the muzzle flow field when the 12.7 mm ballistic gun was fully submerged in water was observed, and the rationality of the numerical model was verified. Based on this, the evolution characteristics of the muzzle flow field at different water depths (h=1-100 m) are analyzed and compared. Through comparison, it is found that within the range of the muzzle flow field, the projectile displacement meets the exponential function with time under different water depths; the deeper the water, the longer it takes for the typical wave structure of the muzzle flow field to form, and the lower the peak temperature and pressure of the gas at the axial Mach disc, the smaller the pressure oscillation amplitude, the faster it stabilizes. but in the radial direction, the deeper the water depth, the longer the duration of pressure oscillations.
$v.latestStateEn doi: 10.11883/bzycj-2019-0445 Read OL PDF (1) Abstract: Based on the field test of environmental vibration characteristics of subway tunnel millisecond delay blasting, considering the irregular characteristics of blasting load, a modified Davidenkov constitutive model based on asymmetric loading and unloading criterion is used to describe the dynamic nonlinear characteristics of the site soil. The transient air shock wave generated by the internal explosion on the surface of cylindrical blast hole is simulated by improving the Friedlander equation. And a three-dimensional refined finite element model of ground-blast-source system, involving the blast wave input and finite/infinite element coupling boundary, is realized. The effectiveness of the model method is verified by comparing with in-situ testing data. The environmental vibration features induced by 50 ms delay blasting and instantaneous blasting are numerically simulated. It is found that millisecond delay blasting can not only effectively reduce the surface peak vibration velocity, but also significantly change the frequency spectrum characteristics of surface vibration. The frequency band of surface vibration produced by millisecond delay blasting is relatively concentrated, which has a significant effect on dispersing blasting vibration energy. Moreover, the main frequency of surface velocity response is higher, which is far away from the natural frequency of building structure, it can significantly reduce the structural vibration level of adjacent buildings caused by blasting construction. The research results reveal the vibration characteristics and vibration reduction mechanism of millisecond delay blasting environment, which can provide scientific basis and reference for blasting construction of subway tunnel in complex urban environment.$v.latestStateEn  doi: 10.11883/bzycj-2019-0435
Abstract:
In the article a thermodynamically consistent diffuse interface model is proposed in order to numerically simulate the interaction between solid explosive detonation and compressible inert media. The chemical reaction of detonation course in solid explosive is simplified as the solid-phase reactant changing into the gas-phase product, thus the mixture within a control volume is regarded to be composed by three kinds of components: solid-phase reactant, gas-phase product and inert media, and all components are thought to be in mechanical equilibrium and thermal nonequilibrium because of their having distinct thermodynamic properties or equations of state. The starting point based on the energy conservation of the mixture and pressure equivalence among components within the control volume is adopted to derive the evolution equation for volume fraction of every component, in which the equation for energy conservation of the mixture is decomposed into a family of equations for energy conservation of the all components with the heat exchange resulting from thermal nonequilibrium. Thus, the governing equations of proposed diffuse interface model include: the conservation equation for mass of every component and the conservation equations for momentum and total energy of the mixture, and the evolution equations for volume fraction of every component and for pressure of the mixture. The important character of the present model is that the mass transfer due to chemical reaction and the heat exchange due to thermal nonequilibrium are involved. In this model, pressure is solved directly from the governing equations instead of computed next from the obtained conservative variables. The present model may apply to arbitrary expression of equation of state and allow for any number of inert media. The partially differential governing equations of the diffuse interface model are numerically solved by a temporal-spatial second-order Godunov-type finite volume scheme with wave propagation algorithm. From numerical examples, the proposed diffuse interface model can eliminate the unphysical oscillations near the material interfaces, and obtain the agreeable results with the physical mechanism.
$v.latestStateEn doi: 10.11883/bzycj-2019-0416 Read OL PDF (4) Abstract: In order to investigate the closed explosion and venting characteristics of gasoline-air mixture, two kinds of explosion modes were studied by using a visualized square tube, and numerical simulation was carried out based on the wall-adapting local eddy-viscosity (WALE) model and Zimont premixed flame model. The results show the followings. (1) The number of the peaks on the overpressure time series curve for the vented explosion is greater than that for the closed explosion, and there is a violent oscillation similar to a simple harmonic vibration on the overpressure time series curve of the vented explosion, while the characteristic parameters of explosion overpressure in the closed explosion are significantly higher than those in the vented explosion. (2) The maximum flame propagation speed in the closed explosion is significantly lower than that in the vented explosion, but the former reaches the maximum at the beginning of flame propagation, while the latter reaches the maximum at the end of flame propagation. (3) Tulip-shaped flame appears in the closed explosion condition, while mushroom-shaped flame appears in the venting condition. The formation of the tulip-shaped flame is related to the coupling effects of flame front, flow field and dynamic pressure of flow field in the pipe, while the mushroom-shaped flame is caused by the combined action of turbulence and baroclinic effect in the external flow field.$v.latestStateEn  doi: 10.11883/bzycj-2019-0398
Abstract:
The scattering of steady-state shear horizontal (SH) guided waves from the elastic strip media with multiple semi-cylindrical depressions on the surface was studied and the analytical solution was given. Firstly, the guided wave expansion method was used to construct SH guided waves. Then, the scattered waves satisfying the zero-stress boundary conditions of the upper and lower surfaces in the strip were constructed by employing the repeated image method. Finally, according to the condition that the shear stress of the edge of the depression is zero, the definite solution equation was derived. The accuracy of repeated image method, the dynamic stress concentration around a depression and the displacement amplitude at the upper and lower boundaries were analyzed by examples. The numerical results show that when there is only one depression, the incident waves with middle and high frequency and the strip with small thickness cause higher dynamic stress concentration around the depression, and the maximum displacement amplitude of the upper boundary occurs near the incident surface of the depression. When there are two depressions, in most cases, the second depression amplifies the dynamic stress concentration around the first depression. And in the ideal elastic strip, even if the two depressions are infinitely far apart, the influence between them still exists.

Abstract:
To evaluate the fast cook-off safety characteristic of the big-size penetrator, an experimental device was designed. The penetrator with a mass of 290 kg was hoisted at a height of 0.4 m from the aviation fuel level for rapid heating. The surface temperature of the penetrator was collected in real time and the whole experimental process was recorded. The reflected shock wave overpressure at a distance of 7 m from the penetrator centroid was measured. The safety characteristic of the big-size penetrator was analyzed in detail in terms of the heating time, the surface temperature of the penetrator, the damage on experimental site, the peak value of the reflected shock wave overpressure, the reaction mechanism and the response type. The results show that the big-size penetrator starts to react violently at a temperature of 537 ℃ for 16 min and 4 s. The bottom explosive of the penetrator first responds to hot spots under continuous high temperature heating, gradually accumulating high-temperature and high-pressure gas in the shell and tearing the shell to quickly release high-pressure. The peak value of the reflected shock wave overpressure at 7 m is 33.622 kPa, which is much smaller than that caused by the penetrator totally detonated in the air. The reaction characteristic of the penetrator is deflagration, and its fast cook-off safety characteristic meets the standard requirement.

Abstract:
Nano titanium carbide (TiC) powder was synthesized by detonation shock utilizing octogen (HMX) as high temperature and high pressure source with titanium dioxide (TiO2) and activated carbon (C) as precursors. The samples were characterized by X-ray diffraction (XRD), energy dispersive spectrometer (EDS) and scanning electron microscope (SEM). At the same time, detonation shock synthesis mechanism of nanometer TiC was discussed in this paper. It was concluded that the test results of XRD and EDS were in good agreement with the theoretical values, and the sample contained both TiC and TiCx (x＜1). The particle size of both TiC and TiCx (x＜1) were less than 50 nm by SEM photos and micron-sized spherical agglomerates were found in the samples. The detonation shock synthesis of TiC belongs to a special solid-phase reaction, and its material diffusion rate and reaction rate are greatly improved.

Abstract:
Research of concrete materials subjected to tensile stress wave at high strain rates is currently based on splitting experiments and spalling experiments with a split Hopkinson pressure bar device, however, they are not appropriate to study the stress-strain relationship of concrete materials subjected to one dimensional tensile stress wave. Therefore, the large diameter split Hopkinson tensile bar (SHTB) is urgently needed to perform direct dynamic tensile study of concrete materials. Mechanical analysis of a new type of SHTB apparatus was performed in numerical simulation method, then corresponding incident tensile stress wave was studied and optimize improvement measures for partial components were also proposed. The partly improved SHTB apparatus reconciled the demands of glued connect mode, hooked connect mode and so on. At last, concrete was considered as a two-phase composite material which composed of coarse aggregates and cement matrix, the annulus three-dimensional concrete aggregate model was established and applied to SHTB simulation experiment. The comparison between numerical simulation results and experimental results verified the effectiveness of partly improved SHTB apparatus, which also provided research directions for dynamic tensile responses of mesoscopic concrete model.

Abstract:
A 37 mm-diameter split Hopkinson pressure bar (SHPB) apparatus was used to conduct impact tests on two types of coral sand to investigate the effect of strain rate. One-dimensional compressive stress-strain curves with the strain rates ranging from 460 to 1300 s−1 were obtained under different compactness levels. Combining with the static compressive results (strain rate of 10−4 s−1), it is found that coral sand is affect with strain rate obviously. Comparison of physical properties of two types of coral sand indicates that the strain rate sensitivity is highly correlated with the proportion of inner pores of the particles and friction between the particles. The calculation models of dynamic intensification factor are proposed, which provide theoretical basis for the numerical calculation of coral sand under impact.

Abstract:
In order to study the crack growth and crack arrest law of the brittle materials, a large-sized trapezoidal opening crack with arc bottom (TOCAB) configuration specimen was proposed. The impact tests were carried out on the TOCAB specimens with radians of 0°, 60°, 90° and 120° under the drop hammer impact device. The crack growth speed was obtained by using the distance between the two resistance wires divided by the break time of the resistance wire of the crack propagation gauge, and crack propagation gauge (CPG) was used to monitor the crack initiation time and expansion time. The crack growth behavior of the TOCAB specimen was numerically simulated by using the finite difference software AUTODYN. And the crack growth process and the crack arrest law were numerically studied. The critical dynamic stress intensity factor of the moving crack was calculated based on the experimental-numerical method and the finite element software ABAQUS. Both experimental and numerical results show that the three arc-bottom specimens have a crack-stopping effect on the moving crack, andthe TOCAB configuration specimen is suitable for studying the crack arrest problem. And the crack growth path obtained in the numerical calculation is basically consistent with the experimental results, which verifies the validity of the numerical model. And the critical dynamic stress intensity factor at the time of crack initiation and crack arrest is greater than that at the time of the crack growth.

Abstract:
With the development of hypervelocity kinetic energy weapons, the mechanism of long rod hypervelocity penetration into concrete target was a research highlight. To study the penetration mechanism and the crater law of long rod hypervelocity penetration into concrete, two kinds of long rods, TU1 and Q235, hypervelocity penetration into concrete with initial velocity of 1.8−2.4 km/s were experimented. Dimensional analyses of crater diameter and crater volume were performed based on the experiment data from this paper and references. Prediction formula of crater depth was derived from the bowl shape contour of crater section. The crater size of hypervelocity penetration was obviously larger than that of low and medium velocity penetration, and so the crater phase was non-negligible during the penetration mechanism researches. The length of the long rod was severely shortened until the long rod was completely eroded, the radius of the hole was obviously larger than that of long rod, and these results can be used to verify that the mechanism of long rod hypervelocity penetration into concrete was semi-fluid penetration. At the same time, it can be seen from the experimental results that the length of the long rod was the most important parameter affecting the penetration depth. The penetration depth increased with the increase of the length and density of the projectile, but was not affected by the strength of the long rod.

Abstract:
In order to study in depth the structural response of the bottom protective component of the vehicles under blast loading and improve the blast resistant performance of the protective vehicles, a finite element model of the bottom protective component of a vehicle under blast loading was established, and the reliability of the finite element simulation was verified by the explosion impact bench test; the concave hexagonal negative Poisson’s ratio honeycomb material was used as the core layer of the protective component, the deformation mode of the negative Poisson’s ratio honeycomb material under blast loading was analyzed, and the blast resistant performance was compared with the other three protective components of the same mass. The results show that the protective component containing negative Poisson’s ratio honeycomb core has better resistance to blast loading. A mathematical model was established for multi-objective optimization problems with the cell size parameters of the honeycomb material as design variables, and the multi-objective genetic algorithm was used to obtain the optimal solution of the cell geometric parameters, which effectively reduces the maximum deflection and maximum kinetic energy of the protective component substrate.

Abstract:
In order to solve the problem of poor performance of EMD (empirical mode decomposition） filter de-noising for vibration signal, an adaptive orthogonal decomposition signal de-noising method PEMD (principal empirical mode decomposition) is proposed. This algorithm combines the self-adaptability of EMD decomposition and the complete orthogonality of principal component analysis (PCA), eliminates the phenomenon of mode aliasing in the process of signal EMD decomposition, and obtains the best de-noising effect. The results showed that compared with EMD and EEMD (ensemble empirical mode decomposition）, PEMD (principal component analysis) improved 1.15 dB and 0.38 dB respectively in the simulation test, and the root-mean-square error was the smallest. In frequency domain, PEMD has the highest sensitivity to the frequency of simulation signal (30 Hz), and the noise filtering effect is the best outside 30 Hz. In the blasting vibration test, PEMD and EEMD had better performance in removing burrs, and PEMD had the best performance in preserving medium and low frequency vibration signals at 0−300 Hz, and the best performance in filtering high frequency noises above 300 Hz.

Abstract:
In order to study the influence of weak dynamic disturbance on rockburst, test on cubic medium-coarse grained granite specimen with a circle hole was conducted to simulate the rockburst ejection process in circle tunnel subjected to weak dynamic disturbance. Three loading paths, namely, no disturbance, weak dynamic disturbance starting at high-stress level, and weak dynamic disturbance beginning at a low-stress level were considered. The testing process was recorded using AE and video monitoring system. The ejection failure process, characteristics of rockburst pit, acoustic emission signal characteristics and rockburst intensity were investigated. The testing results show that the weak dynamic disturbance can reduce the stress level at the occurrence of rockburst and increase the range of rockburst. The applied dynamic disturbance at a high-stress level leads to a rapid occurrence of rockburst. In contrast, when the weak dynamic disturbance is applied at a low-stress level, rockburst will occur in a gradual manner. In addition, compared with that without dynamic disturbance, rockburst with the weak dynamic disturbance starting at high-stress level has a higher intensity, while that with weak dynamic disturbance starting at low high-stress level has a lower intensity. This is because that weak dynamic disturbance starting at high-stress level is capable of stimulating and amplifying the energy release process, while weak dynamic disturbance starting at a low-stress level is only capable of stimulating the energy release process.

Abstract:
In the process of freezing vertical shaft blasting, the baseline drift and noise in the near area monitoring signal have significant influence on the fine extraction of local characteristics. On the basis of effective acquisition of shaft lining vibration signals in near field of blasting, complementary ensemble empirical mode decomposition (CEEMD) method, baseline estimation and de-noising with sparsity (BEADS) method and hidden Markov model de-noising (HMMD) method and so on are used to solve the problem of baseline drift and random noise elimination in the signal, and the correlation evaluation of correction and noise elimination effect is carried out by cross wavelet transform (CWT). The analysis results show that: the slowly changing baseline component in the signal exists the whole process of each modal component, and it is mainly concentrated in the low frequency component, while the noise is concentrated in the high frequency component. The combined analysis method can deal with low frequency baseline drift and high frequency noise effectively. It is an efficient and relatively amplitude-preserving signal analysis method, and can be used to preprocess of batch blasting vibration signal data.

Abstract:
To analyze the effect of porous materials on the explosion characteristics of premixed gas, a self-built explosion experiment platform was used to investigate the behavior of porous materials with different porosities and thicknesses on premixed methane/air gas explosion with a stoichiometric ratio of 1. Experimental studies have shown that porous materials with different porosities can either promote or suppress the explosive flame and overpressure. When the porosity was low, the propagation speed of the deflagration flame decreased with the increase of material thickness, and when the thickness was large, the flame had a short propagation delay. When the porosity was high, the quenching effect occurred when the premixed flame impacted the porous material. However, in the following period, due to negative pressure suction, diffusion combustion occurred on the surface of the material towards the side of the exploded area, and the degree of diffusion combustion was inversely proportional to the thickness of the material. The solid phase structure of porous materials could reduce the efficiency of pressure release and absorb energy, resulting in increasing the rate of explosion overpressure rise and reducing the overpressure peak. When the porous material with δ=10 were used to promote flame propagation, compared with premixed gas explosions with a stoichiometric ratio of 1, the peak overpressure could be increased by about 2 times at most, causing more serious consequences. Quenching occurred when flame impacted the porous material with δ=20, and the maximum overpressure attenuation was 47.17%. The maximum overpressure decreased by 24.62% at the porous material with δ=30.

Abstract:
The dynamic response of buried high density polyethylene (HDPE) bellows under blasting seismic load was studied. First, the blasting test of buried pipeline was carried out by combining the blasting seismic test and dynamic strain test. Secondly, the dynamic response characteristics of buried pipeline under blasting seismic load were analyzed. Then, the characteristics of vibration velocity and dynamic strain distribution were studied. Finally, the pipe safety was evaluated based on the von Mises yield criterion, and the blasting vibration velocity control standard was proposed. The experimental results show that the vibration velocity of pipeline and ground and the dynamic strain of pipeline increase with the decrease of core distance and the increase of explosive quantity. The dominant frequency of blasting seismic wave is higher. The dominant frequency of pipeline is higher than the surface. Under the same blasting condition, the ground vibration velocity above the pipeline is generally higher than that of the pipeline. The peak axial strain on the back explosion side of the pipeline section is mainly tensile strain, and the peak circumferential strain on the front explosion side is mainly compressive strain. The vibration velocity of the pipeline can be safely controlled by 20 cm·s−1, and the pipeline is in a safe state.
