摘　　要：论述了沉底雷仪表锅在水下爆炸作用下的冲击损伤。简要介绍了试验工况、计算模型、计算条件等,对沉底雷仪表锅在水下爆炸作用下的实际损伤与仿真结果进行了对比;研究了冲击毁伤与载荷强度、炸药之间的关系,并应用圆柱壳屈曲理论讨论计算仪表锅结构冲击损伤的方法;提出了应用表面平均总压力来表征爆炸载荷强度,为今后的水雷爆炸试验提供参考。This paper discusses shock damage of instrument cylinder of seabed mine subject to underwater explosions. It introduces test conditions,finite element model and calculation parameters,compares the actual damage of the instrument cylinder with the simulation result,and investigates the relations of shock damage,loads intensity and explosives. It also discusses the method of calculating structure shock damage of instrument cylinder using the theory of Buckling Strength for Cylindrical Shell and puts forward the method of using overall average surface pressure to represent explosion load intensity,which provides good reference for future explosion tests for sea mines.
