球形头部弹丸侵彻运动靶板的数值模拟
Numerical Simulation of Spherical Head Projectile Penetrating into the Moving Target
摘要
Abstract
In order to study the penetration rule of high velocity spherical head projectile penetrating into the moving target plate,using LS-DYNA dynamic analysis software simulating and studying the effect of the spherical head projectile on the target penetration in different conditions. The response of how the the thickness of the moving target,the material and the velocity of the projectile three factors affect the projectile trajectory,the turning angle and the residual velocity in the penetra-tion process is obtained. Results show that with the increase of speed,the amplitude and the offset of the projectile are gradually reduced. With the increase of the thickness of the target plate,the forward turning angle and the axial velocity of the projectile are significantly reduced and the trajectory offset increases. Of the three materials,the 4340 steel target is the biggest influence on the trajectory deviation,the turning angle and the residual velocity of the projectile,the second is Weldox460 stell, and the least is LY12 aluminum.关键词
