摘　　要：在分析反鱼雷硬杀伤武器水下爆炸作用下鱼雷自身毁伤机理的基础上,建立反鱼雷硬杀伤武器的水下爆炸载荷计算模型及鱼雷结构毁伤计算模型。在使用声-固耦合技术实现水下爆炸冲击波作用于鱼雷壳体条件下,提出典型双面背水片状结构通过分布载荷实现耦合加载的方法,以解决鱼雷壳体与螺旋桨、舵等典型结构在水下爆炸作用下的耦合计算问题。结果表明:雷体上的典型片状构件更易于雷体本体毁伤;该方法可用于水下爆炸作用下鱼雷典型结构的毁伤特性分析以及鱼雷内部的冲击环境预报,为鱼雷易损性分析及模型的建立、毁伤等级的确定奠定基础。On the basis of analyzing the damage mechanism of torpedo subjected to underwater explosion of anti-torpedo weapon,the damage calculation models of torpedo structure and the underwater explosion load calculation models of anti-torpedo weapon are established.A coupling loading method,in which the acoustical-structure interaction on torpedo shell and the distributed force addition on typical structure of two sides with water are considered,is proposed to solve the coupling calculation problems.The results show that the typical flaky structure is damaged more easily than torpedo shell.The proposed method can be used for analyzing the damage characteristics of propeller and rudder and predicting the shock environment inside torpedo under underwater explosion.
