主要通过数值模拟技术仿真霍普金森压杆获取试件更大的加速度峰值。采用双锥形子弹作为实验发生装置,仿真分析结果发现以相同的子弹速度撞击压杆,随着双锥形子弹中间段直径的增加,试件的加速度峰值也随之增加,试件的加速度脉宽不变;增加子弹上表面直径和中间段直径获得的试件加速度峰值比增加子弹下表面直径和弹长获得的加速度峰值更大。

In this paper, the simulation technology is used to simulate the higher acceleration peak of the specimen with the hope of Golden Sen. The double cone bullet is used as the experimental device, the simulation results show that with the same bullet velocity impacting the compression rod, the acceleration peak of the specimen increases with the increase of the middle diameter of the double cone bullet, and the acceleration pulse width of the specimen is invariable. The acceleration peak value of the specimen obtained by increasing the surface diameter and the intermediate diameter of the projectile is greater than that of increasing the surface diameter and the length of the projectile.
