摘　　要：用于鱼雷爆炸毁伤考核的靶标设计目前没有标准规范可供参考,只能参照舰船毁伤评估现有方法,对毁伤考核靶标进行设计.首先从原理上分析水面舰船毁伤等级划分依据,明确毁伤考核靶标的设计应参照舰船结构的不同破口、塑性变形等损伤失效情况,同时指出考核靶标设计过程中借鉴现行舰船毁伤等级标准存在的问题;通过仿真计算解决该难点,结果表明水下爆炸载荷与典型水面舰船存在复杂耦合作用,鱼雷爆炸毁伤效能不仅与爆炸载荷对船体的做功能力相关,还与载荷的作用模式、能量的输出结构相关,不同工况下毁伤模式、能量输出结构存在较大差异,应根据计算结果所预报的对应工况下的毁伤模式、能量的输出结构开展水下爆炸靶标结构的设计;针对鱼雷爆炸毁伤特点提出水下爆炸靶标结构优化设计方法,同时通过仿真计算对靶标设计毁伤的等效性进行了验证,仿真对比显示依据该方法设计靶标能够有效评判鱼雷对实船爆炸毁伤效果,给出实战条件下鱼雷爆炸毁伤靶标设计流程,为鱼雷爆炸毁伤评估靶标设计提供技术支撑,该方法同时能为鱼雷爆炸毁伤试验考核提供仿真预报.There is no standard specification for targeted design based on the torpedo explosion damage assessment. Existing methods are currently based on ship damage assessments. We analyze the basis for the classification of damage levels of surface ships, which clarified that the design of the damage assessment target should refer to the damage and failure conditions of the ship structure such as different breaks and plastic deformation, and point out the problems around drawing on the current ship damage rating standards in the process of assessing target design. In this work, these issues are resolved through simulation, and the results show that there is complex coupling between underwater explosion loads and typical surface ships. Torpedo explosion damage efficiency is not only related to the physical work of the explosive load on the hull but also to the mode of action of the load and the energy output structure. The damage mode and energy output structure are quite different under different working conditions. The design of the underwater explosion target structure should be carried out based on the damage mode and energy output structure under the corresponding working conditions predicted by the calculation results. According to the characteristics of torpedo explosion damage, an optimized design method for the underwater explosion target structure is proposed. The equivalence of target design damage is verified through simulation. The simulation comparison shows that the design of the target, based on this method, can effectively evaluate the damage of the actual ship by the torpedo. The design process for the torpedo explosion damage target under actual combat conditions is given to provide technical support to the torpedo explosion damage evaluation target design. This method can also provide simulation prediction for torpedo explosion damage test assessments.
