中文摘要：
根据考核工况药包的设定及冲击波的传播特性,计及冲击波的水面截断效应及平台底部的局部空化现象,给出平台在球面冲击波作用下的垂向刚体运动计算方法.通过数值仿真计算及相关试验数据,验证了计算模型的合理性及仿真计算的有效性.对于刚度较大的浮动冲击平台,其垂向刚体运动速度在总体响应中占有较大比例.理论计算模型及分析结果为舰用设备抗冲击能力的评估和新型浮动冲击平台的设计提供参考.
英文摘要：
According to the charge set of assessment conditions and the characteristics of shock wave propagation,with account of the surface truncation effect of the shock wave and the local cavitation at the bottom of the platform,the calculation method of vertical rigid body motion subjected to spherical shock wave was given.Through the numerical simulation and the related experimental data,the rationality of the calculation model and the effectiveness of the simulation calculation were verified.For floating shock platform with large stiffness,its vertical rigid motion speed in the overall response has a large proportion.The theoretical calculation model and the analysis results provide the reference for the impact resistant ability evaluation of marine equipment and the design of new floating shock platform.
