| 摘 要： | 简要地总结了关于动力屈曲问题的研究成果和有关理论，重点介绍了结构冲击屈曲问题的研究现状。按照穿甲弹风帽的形状特点与受力特点，建立了风帽的冲击屈曲简化力学模型及其动力稳定基本方程，并用Ляпунов动力准则，导出了风帽冲击屈曲时的临界荷载、自振频率和临界时间的近似计算式。这不仅解决了穿甲弹风帽冲击屈曲的近似计算问题，而且还可用于截顶锥壳的动力屈曲问题。

| Abstract: | In this paper,the findings of research and related theory on the impact backling are summarized, the actual state is introduced.According to the shape and stress feature of ogive, the abridge mechanics model and the stability basic equation are obtained. The approximate calculation formula on the critical load and self-oscillation frequency and the critical time are derived through Lyaponov dynamic criterion. The method is used to solve the approximate calculation of impact buckling,and can be used to settle the dynamic buckling of truncated conical shell. |
