| 摘 要： | 把箱装弹药简化为二自由度系统，将包装箱及弹体等效为线弹性材料，基于Matlab数学软件，运用四阶龙格-库塔法对系统进行数值分析，分别讨论了频率比、包装箱阻尼、质量、弹性系数、保险簧弹性系数以及跌落高度对保险元件冲击响应的影响。所得结论对弹药科学储运具有指导意义。

| Abstract: | Packaged ammunition was predigested to double degree system. Packaging box and ammunition body was considered the equivalent of linear elasticity material. Numerical analysis was carried out on the system with fourth order Runge-Kutta method and Matlab software. The influences of frequency ratio, package damping, package mass, package elasticity coefficient, safety spring elasticity coefficient, and dropping height on impact response of safety elements were discussed. The purpose was to provide reference for storage and transportation of ammunitions. |
