摘　　要：以水下非接触爆炸环境为研究背景，在论述隔冲原理及粘弹性材料力学特性的基础上，分析了粘弹性复合材料隔冲结构的各种非线性因素，根据物理样机的实际工况，建立了粘弹性复合材料隔冲结构的有限元模型，仿真计算得到了瞬态激励条件下隔冲结构的动力衰减曲线。为隔冲结构设计提供了依据，并为进一步研究以时间和温度双标量为参数的粘弹性材料动力学特性提供了参数。With the research background of underwater non-contact explosion condition, based on the presenting of shock-isolation theory and viscoelastic materials mechanical characteristics, the paper analyzes the nonlinear problems of shock-isolation structures of viscoelastic composite materials. The finite element model of shock-isolation structures based on the actual working conditions of physical prototype is built. The dynamical decay curves of shock-isolation structures in the condition of transient excitation is obtained with simulatidn. A foundation is given for the design of shock-isolation structures and the parameters are the provided for further study of viscoelastic materials dynamical characteristics with double scalar quantity which are the time and the temperature.
