摘要

摘要: 针对传统水下爆炸冲击响应实验研究中存在的问题, 提出了一种实验室仿真水下爆炸冲击的等效加载方法, 通过飞片撞击的方式来获得水下爆炸冲击等效载荷。同时建立了等效理论模型与流固耦合数值仿真来进行对比分析。结果表明, 数值仿真结果与理论分析结果吻合较好, 通过调节飞片的撞击速度与撞击比质量可以获得不同水下爆炸冲击所需要的等效载荷, 进而为鱼雷爆炸对典型舰船结构的冲击响应研究提供一种新的思路。

Abstract: An equivalent loading method for laboratory simulation is put forward to solve the problems in existing ex-perimental studies of underwater explosion impact response. In the new method, flyer impact is adopted to achieve the equivalent load of underwater explosion. An equivalent theoretical model is established, and its analysis result is com-pared with that of the fluid-solid coupling numerical simulation. The comparison shows that both results agree well. By using this theoretical model, the required equivalent load for different underwater explosion impact can be achieved by adjusting the flyer′s impact velocity and specific mass of impact. This study may provide a new idea for research on torpedo explosion impact response of typical ship structure.
