Abstract

Abstract

Aimed at acceleration information acquisition and original signal failure problem of projectile penetrating into concrete, a projectile-borne storage testing system was used to conduct test, and the numerical simulation of high-velocity impact was carried out based on LS-DYNA, and the processed data curve corresponds to the measured penetration depth.The numerical simulation results and testing results are in good agreement, which indicates the correctness of this numerical simulation model establishment and parameter selection.The influence analysis of original acceleration signal is conducted on stress wave, fundamental motion of testing device, installed structural stiffness, installation way of accelerometer and some other influencing factors by way of combining test analysis with theoretical derivation, and the results of analysis have certain reference value for high-g-value shock test problem.
