目的 研究公路运输条件下典型弹药系统的基本振动特性。方法 以某典型弹药系统为对象，设计运输振动模拟试验测试弹体和关重件的振动加速度响应，进而分析各层弹药系统的功率谱密度和振动传递率。结果 下层弹药和弹体振动响应激烈，振动传递具有多模态性，有明显的主次之分，最大传递率分别为5.681和4.054。结论 试验结果为我军同类弹药系统运输包装的改进和设计提供了基本数据。

To analyze the basic vibration characteristics of typical ammunition system during highway transportation. Based on a typical ammunition system, the transportation vibration simulation experiment was designed to test vibration acceleration response of projectile body and key element to future analyze PSD and vibration transmissibility of ammunition system in each layer. The response of bottom ammunition and projectile body were prominent, and the vibration transmissibility had multiplex modes of apparent primary and secondary features. The peak transmissibility was 5.681 and 4.054 respectively. The results provide basic data for packing improvement and design of similar ammunition system in highway transportation.
