摘　要：利用TiNi形状记忆合金材料及橡胶高聚物，组合设计了适用于潜艇平台的可反复使用的抗冲击装置，并对其在不同冲击脉宽和峰值作用下的抗冲击特性进行了数值研究，结果表明该抗冲击装置对冲击加速度的衰减高于95%，可以对100kg左右的机电设备提供有效的抗冲击防护。将该装置与传统的线性弹簧抗冲击系统进行了比较，其相对变形量及加速度响应均小于线性抗冲击系统，更为重要的是，变形过程中的能量滞回能够有效的衰减振动能量，使振动幅值迅速减小。

Abstract: By using a composite structure of Titanium Nickel shape memory alloy(SMA) and rubber polymer, a repetitive-use shock resistance device for submarine platform was designed. The shock resistance characteristics of this device subjected to different pulse durations and amplitudes were simulated numerically with the ansys/ls-dyna finite software. The results show that the shock acceleration attenuation of this device is up to 95% or more, and it can protect the equipment of about 100kg effectively against the shock loading. Compare with the traditional linear spring, it has lower acceleration response and vibration amplitude. Most important, for the hysteretic characteristic from superelastic deformation of SMA, it can attenuate the vibration amplitude rapidly.
