抗冲瓦的优化设计研究

敷设于舰船湿表面上的抗冲瓦可以有效提高舰船的抗水下爆炸冲击性能。本文从抗冲瓦的结构拓扑参数方面来研究其抗冲击特性，讨论了不同强度冲击载荷下抗冲瓦的优化设计区域，提出了拓扑结构、应力平台与结构密度三参数优化设计方法，最终给出了一种较为优化的结构形式。

Optimization Design of Anti-shock Coating

In order to improve the underwater explosion impact resistance performance, hyper-elastic anti-shock layer could be adhered to the ship wet surface. Structure parameters and blast-resistant characteristics of anti-shock layer are investigated, and the optimal design region of the anti-shock layer under different impact loads is discussed. The optimal design method of three parameters, which include topology structure, stress platform and structure density, is proposed. The dynamic response of hull structure with anti-shock layer subjected to far-field underwater explosion has been studied, and then the effect of anti-shock layer optimization design evaluated and confirmed by the simulation results.
