摘　　要：GJB1060.1-91《舰船环境条件要求-机械环境》中要求海军舰船设备均需进行抗冲击设计及试验验证。而大型舰船设备由于尺寸、重量过大,存在难以进行实物冲击试验考核的问题。针对这一问题,该文以某舰船蓄电池组为研究对象,采用动力学设计分析方法(DDAM)对该蓄电池组结构强度进行三个方向的冲击仿真计算并进行校核。计算结果表明:采用ANSYS的DDAM仿真计算方法可准确分析计算冲击作用下结构的应力水平,从而找到蓄电池组的薄弱环节,为其结构的优化改进及舰船设备的抗冲击性能提升提供参考。Shock test and design is used to verify the quality of naval equipment according to the GJB1060.1-91 General Requirement for Environmental Conditions of Naval Ships Mechanical Environments.It is too big and heavy to impact the real naval equipment.The structural strength of storage battery under shock test is simulated and calculated by using the dynamic design analysis method(DDAM)based on ANSYS.The structural stress of storage battery is calculated by using DDAM,and the weakness of storage battery structural also can be located.It provides a reference for the optimization and improvement of structure and the impact resistance of naval equipment.
