| 摘 要： | 对Brinson的本构模型作了适当的修正,建立了适用于形状记忆合金弹簧的本构模型。基于该本构关系,还进行了形状记忆合金弹簧的变形分析,可以看出SMA弹簧在不同的状态下,其刚度也不同,这样可通过改变SMA弹簧的刚度来改变系统的共振频率。

| Abstract: | In this paper, the constitutive model by Brinson (1993) is modified, and the constitutive model suitable for shape memory alloy (AMS) springs is built. Based on the constitutive model, the deformation of SMA springs is analyzed. It can be seen that the stiffness of SMA springs is variable under different load and temperature conditions, therefore changing the stiffness of the SMA springs can easily control the resonance frequency of a system. |
