摘　　要：通过静力学分析,忽略接触摩擦,将火工品包装箱的抗震性能分析转化为线性动力学问题,建立了有限元模型并分析模态,得到了前20阶振动频率,在此基础上对包装箱进行了随机振动和水平冲击测试。该方法对优化火工品包装箱设计以提高箱体结构的抗震性能,具有实际意义。The vibration resistance analysis on packing case of Initiating Explosive Device（IED） was transformed into linear dynamic issues by using static analysis and ignoring the contact friction.The finite element model was consequently established.Front 20 orders vibration frequencies were obtained.Packing case of IED was tested by random vibration test and horizontal impact test.The method can be applied to optimize the design of packing case of IED to improve vibration resistance.
