选取典型空中爆炸载荷工况，应用ls-dyna实时模拟空中爆炸载荷，研究不同结构形式对水密门冲击响应的影响。通过对2种结构水密门设备分别进行抗冲击实例计算，实现了水密门结构在空爆冲击下的运动响应过程。对比研究结构最大应力、应变特征参数，分析得出不同结构水密门最大应力位置规律及结构冲击特点，获取水密门设备最大响应位移，指出板架加强结构可以有效地减小水密门整体最大应变值和最大位移，为舰载设备抗冲击分析、优化设计提供技术路径。
The typical airborne explosive load conditions are selected, and ls-dyna is used to simulate the airborne explosion load in real time. The influence of different structural forms on the watertight door impact response is studied. The watertight door structure is realized by calculating the impact resistance of the two structural watertight door devices respectively. In the motion response process under air-explosion impact, the maximum stress and strain characteristic parameters of the structure are compared and analyzed. The maximum stress position and structural impact characteristics of different structural watertight doors are obtained. The maximum response displacement of watertight door equipment is obtained, indicating that the plate reinforcement structure can be effective. The overall maximum strain value and maximum displacement of the watertight door are reduced, which provides a technical path for the impact analysis and optimization design of the shipborne equipment.
