摘要

 针对舰船的含声学覆盖层结构,对水下爆炸作用下应力波在该结构中的传播规律进行研究。采用二阶Godunov方法,建立水下爆炸应力波在多层介质中传播的计算模型,并与经典Taylor平板解析解进行对比验证;通过对不同工况下的应力波传播规律分析,获得边界条件、声学覆盖层厚度等参数对其影响规律,可为舰艇抗冲击设计、研究提供参考。

Abstract

Coated plates are widely used in naval ship structure for better protection from underwater explosion. Further understanding of wave propagation mechanism in multilayered mediums is very significant. A second-order Godunov method is used to establish the calculation model for wave propagation mechanism in the coating plate subjected to underwater explosion. The numerical results are in good agreement with Taylor’s solution. Different boundary condition and thinness of the coated plate are analyzed to obtain the effects on the coated plates. The results offered a reference for designing and studying submarine's shock resistance.
