| 摘 要： | 用动光弹实验方法研究了冲击荷载作用下穿甲弹风帽模型的应力波的传播过程，对其受冲击后的动应力状态进行了分析，用应力光学定律得到了模型内的动应力值。并根据应力波理论，推导出了风帽受冲击荷载作用时动应力的理论近似解，计算结果与实验结果非常一致。另外，这种方法还为改进风帽的结构设计提供了有益的建议。

| Abstract: | In this paper, a dynamic photoelastic method is applied to investigating the stress wave propagation of projectile ogive under impact load, the dynamic stress state is analyzed, and the dynamic stress values are obtained by applying stress optics law. Based on stress wave theory, the analytic approximate solution is obtained. The calculated results correspond with experimental result. This method can be used to evaluate the destructive mechanism and to improve the structure well of projectile ogive under impact load. |
