Abstract

Abstract

To solve the bottleneck problems such as the high cost of charge safety and reliability test and the difficulty of strong overload environment test, the overload environment of the charge when a projectile penetrates a steel plate was simulated using AUTODYN finite element numerical simulation software, aiming at the equivalent simulation of the overload environmental force of the internal charge when the projectile penetrates the steel plate. Based on the parameters of the waveform, pressure peak, and pulse width obtained from the simulation, a charge loading simulation experimental device composed of an initiation system, loading system, auxiliary system, and pressure test system was designed, and the charge overload environmental force equivalent simulation experiment was carried out. To a certain extent, the equivalence of the charge loading state, when the experimental system simulated the projectile penetrating the steel target at a speed of 500−1200 m/s, was verified, which broke through the requirement that the loading pressure was greater than 1 GPa and the pulse width was greater than 100 μs. The results indicate that the overload pulse received by the projectile penetrating the steel plate charge is a sine wave single pulse. The waveform adjuster can not only regulate the generated waveform but also have a significant impact on the attenuation of pressure values. As the thickness of the waveform adjuster increases, the pressure loaded on the surface of the test drug gradually decreases, and the pulse width significantly increases. As the thickness of the flyer increases, the driving speed obtained by the flyer gradually decreases, and the pressure loaded on the surface of the test drug significantly decreases, with no significant change in pulse width. The comparison between the pulse characteristic values formed by the loading simulation test device and the numerical simulation results of the projectile penetrating the steel target shows that the maximum error of the overpressure peak is 5.71%, and the maximum error of the first peak pulse width is 14.8%, both lower than 15%. This verifies the equivalence of the loading state of the propellant when the test system simulates the projectile penetrating the steel target.
