为更好地分析复杂环境中箱装弹药跌落过程的动力学响应,基于非线性有限元理论建立箱装弹药动力学有限元模型。建立5种典型特性地面有限元模型;仿真计算得到不同地面特性下的箱装弹药关键部件的应力和加速度数据,分析不同地面特性对应力和加速度的影响。分析结果表明:该方法可为摔箱弹等事故处理提供参考依据,也可为弹药包装箱优化提供一种设计思路。

In order to better analyze the dynamic response of ammunition dropping in complex environment,the dynamic finite element model of ammunition was established based on nonlinear finite element theory.5 kinds of typical ground finite element models were established,and the stress and acceleration data of the key components of the boxed ammunition under different ground characteristics were obtained by simulation calculation,and the influence of different ground characteristics on the stress and acceleration was analyzed.The analysis results show that this method can provide a reference for the accident treatment of ammunition falling box,and also provide a design idea for the optimization of ammunition packing box.
