摘要
形状记忆合金是近期发展起来的新型功能材料 ,在土木工程中的应用尚处于起步阶段。以Brinson本构模型为理论依据 ,建立了阻尼器的热力学非线性方程及其求解方法 ,并利用MATLAB编制的计算机软件进行了实例仿真。计算结果表明 ,形状记忆合金阻尼器具有较强的耗能能力。由于形状记忆合金在不发生塑性变形的情况下可以获得较大的滞回变形 。
Shape memory alloys is a new style function material developing currently its application is only in starting stage in civil engineering. According to theory of Brinson's constitutive model, damper's thermodynamical nonlinear equation and its extracting method was developed here. Emluator have been compiled with MATLAB, and it was applied to actual SMA damper, the calculating results indicate that SMA damper have a large energy absorbing capacity. Because it is possible to achieve large hysteretic deformation in SMA without incurring plastic deformation, SMA is ideal material for use in earthquake engineering passive control.
