| 摘 要： | 采用LS-DYNA动力学仿真软件对某半穿甲子母战斗部3 m高度以不同跌落方式自由落体进行了数值模拟计算.通过计算，得到在不同状态下战斗部跌落时的结构应力变形和装药过载响应数据.结果表明，战斗部大端朝下垂直跌落时内装子弹装药所受过载最大，安全性威胁较大，为后续战斗部跌落试验提供了一定的参考.后续战斗部跌落试验和数值模拟结果较为相符.

| Abstract: | The 3 m drop impact of semi-armor-piercing cluster warhead is simulated by nonlinear finite element software ANSYS/LS-DYNA and a verification test is conducted. The structural distortion and the acceleration of explosive are obtained under different conditions. The results show that the acceleration of projectile explosive is the largest when the large end of the warhead falls vertically downward, which provides guidance for the following experiment. The simulated results agree well with the experiment data. |
