摘要
针对形状记忆合金伪弹性弹簧恢复力提出分段线性模型， 并藉此对其减隔振作用进行了数值模拟对比计算． 结果表明，这种减隔振装置对较强烈的振动有很好的抑制作用． 控制温度可使系统处于最佳工作状态．
Proposes a piece wise linear mode to simulate the pseudo elastic restoring force of SMA and uses it to do numerical simulation for the response of a vibration reduction system composed of SMA to base excitation. The result reveals that this kind of vibration\|absorbing system behaves good to relatively intensive excitation and even the best if controlled by temperature.
