摘要
运用ANSYS软件对形状记忆合金(SMA)复合材料板簧进行模态分析。首先,建立SMA复合材料板簧的有限元模型;然后,针对升温和降温两个过程分别对SMA复合材料板簧进行模态分析。分析结果表明了温度、SMA纤维含量对复合材料板簧的固有频率以及模态振型的影响,揭示了SMA复合材料板簧的固有频率随着温度的升高而逐渐变大等规律。
The modal analysis of composite leaf spring with SMA was carried out by the ANSYS software. First,a FEM modal of the composite spring was established,and then the modal analysis of the composite spring correspond to heating and cooling was conducted, respectively. Numerical results show the influence oI temperature on the natural frequency and the modal shape of the composite spring. The influence of volume content of SMA fiber on the natural frequency and the modal shape of the composite spring was also investigated. The natural frequency of composite leaf spring with SMA is larger with the rising of temperature and so on.
