摘　　要：为正确评估跌落冲击对弹药安全性的影响,合理设计弹药参数及包装结构,科学指导弹药勤务处理,将引信元件定义为关键部件,采用有限元分析软件ANSYS/LS-DYNA对箱装弹药跌落过程进行计算机仿真,模拟跌落条件下作用于引信元件处的冲击加速度值,并且通过试验验证了仿真模型的可靠性。In order to exactly estimate the effects of dropping impact on ammunition safety, choose reasonable parameters for the ammunition design and package design, and instruct the ammunition service management scientifically, the fuze is defined as a key part in this paper and the ammunition package dropping process is simulated on computer by use of the finite dement analysis software, ANSYS/LS - DYNA, to simulate the acceleration on the fuze and test the rdiability of the modal through experiments.
