摘　　要：当振动系统确定后其响应取决于载荷。对于动态载荷,系统的响应不仅与载荷的持续时间及载荷最大值有关,而且与载荷随时间变化的形状有关。对于同一振动系统,载荷持续时间及最大值完全相同,响应也不一定相同,这决定于载荷上升时间(即"力型"),从理论上讨论了"力型"对振动系统响应的影响,并通过实例计算,证明了理论分析的正确性。其研究对火炮结构系统及载荷设计和响应分析具有指导意义。The response depends on load after vibrating system determined. In regard to dynamic loading, system response depend on not only time and magnitude of load but also curve of load with time. For iden- tity vibrating system, it has same duration and maximum of load but different response, but depend on climbing time of load （load shape）. Theoretically analyses the vibrating system response on different load shape, and example calculation shows the correctness of theoretically analysis. This study is important to design machinery system, load and response analysis of gun.
