| 摘 要： | 从工程中一种常见机器隔振模型出发,推导出了系统传递功率流表达式.计算模拟形状记忆合金的超弹性循环曲线并计算了TiNi形状记忆合金丝加卸载循环时的超弹性等效阻尼,并据此将合金丝作为一种等效阻尼材料应用到隔振模型中.通过计算机仿真,得出在此模型中使用记忆合金丝作为阻尼材料时不同的环境温度和系统振幅对模型隔振效果的影响.

| Abstract: | In this paper from the beginning of a kind of familiar vibration isolation model of mechine in the engineering,we work out the expression of the power flow.And we calculate equivalent damp of super-elastic effect of TiNi Shape Memory Alloy through simulating its cycle curve.According to super-elastic effect of TiNi shape memory alloy,we apply the alloy threads to the model as a kind of equivalent damp material.And we analyze the effect of vibration isolation while applying SMA thread as damp material.under different temperature and displacement. |
