摘　　要：目前,浮筏技术在水面舰船和潜艇上的应用已越来越广泛,其冲击安全性是浮筏应用的一项重要指标之一.该文利用MSC/NASTRAN程序的计算求解器和单元库,应用PCL语言编制前后处理程序,将减振元器件冲击特性数据库和计算软件包进行无缝连接,实现了减振元器件非线性冲击特性模拟和浮筏系统冲击动响应分析方法数据前后处理自动化、标准化,提高了计算效率,利于非抗冲击专业人员进行浮筏系统的抗冲击设计使用.并采用1:1实尺度浮筏系统在浮动冲击平台上进行了水下爆炸试验,考核了浮筏系统非线性冲击动响应计算软件包,固化了浮筏系统的计算方法,考核结果表明,该软件包具有较大的工程应用价值.Presently, raft technique is applied widely to naval vessel and submarine, its＇ shock security is one of important guide lines about raft＇s application. This paper uses solver and element databank of MSC/NASTRAN program, pre-processor and post-processor which compiled with PCL language to link absorber＇s shock characteristic databank with calculate software package closely, then robotization.standardization of absorber＇s nonlinear shock characteristic simulation and raft system＇s shock dynamic response analytical method are achieved, thus calculational efficiency is improved greatly, all of these are propitious to non -anti -shock professiona＇s anti -shock design of raft system Also in order to check calculate software package and fixup the calculation method, in the floating shock platform, an experiment about a raft system on a scale of 1：1 objected to underwater explosion is carried out, experimental results indicate this software package has a better engineering aonlication value.
