摘　　要：根据中型浮动冲击平台系统的使命任务及使用环境,设计了主要包括平台分系统、布放与回收分系统及辅助分系统的系统组成;采用数值仿真计算方法,对板-梁结构、高舷墙板-箱型梁结构和低舷墙板-箱型梁结构3种典型浮动平台结构在水下爆炸冲击下的最大变形进行了仿真计算。结果表明,低舷墙板-箱型梁结构能够满足结构强度要求。在低舷墙板-箱型梁结构的中型浮动平台中放入不同质量的被试设备,对其冲击环境进行了仿真分析,并将计算结果与德国BV043/85规范中的要求值进行了对比分析。结果表明,设计的中型浮动冲击平台的冲击环境满足试验考核要求。Medium floating shock platform is an experiment device which is mainly used to evaluate the anti-underwater explosion shock performance of shipborne equipment with weights of 3.35-181.4 t installed in the platform body in marine environment.The medium floating shock platform is mainly composed of platform subsystem,deployment-recovery subsystem,and auxiliary subsystem.The platform subsystem includes the main body of the platform,deck simulator and platform top cap.The maximum deformations of three typical floating platform structures,i.e.plate-beam structure,high bluge-box beam structure,and low bulge-box beam structure,under underwater explosion impact are simulated by numerical simulation method.The results show that the structural deformation of low bulge-box beam structure made by 921A steel is the smallest and meets the structural strength requirements.Meanwhile,the impact tests for shipborne equipments installed on the low bulge-box structure platform with weights of 30 t and 80 t are carried out.Compared with the requirements of German BV043/85,the calculation results indicate that the impact environment of the medium floating shock platform designed in this paper meets the test assessment requirements.
