水下爆炸冲击载荷作用下加筋复合材料浸潜壳体结构的动力响应

Dynamic response of stiffened composite submersible hull subjected to underwater explosive shock

对加筋复合材料浸潜壳体结构在水下爆炸冲击载荷作用下的动力响应采用LS-DYNA进行了分析,给出沿纵向分布的不同单元的应力时间历程曲线,并给出了位移、应力以及冲击压力波传播云图。

This paper deals with the dynamic response analyses of stiffener composite submersible hull subjected to underwater explosive shock. The finite element program of LS-DYNA are employed in the analyses. Curves of stress-time history for some elements distributed along the length are provided, and the distribution of displacements and stress, the propagation of the shock pressure are gave.
