摘　　要：将CuZnAl形状记忆合金用于框架结构的减振控制,试验结果表明,可使框架具有较大的阻尼比,利用Matlab的Simulink模拟框架的振动情况,通过计算所得框架的阻尼比调整修正各个模块参数,得到的框架振动计算机模拟结果与实际测得曲线相符。同时建立了地震波和风载荷模型,并作为外加载荷输入框架振动的计算机模型。Experimental results showed that the frame have larger damp ratio when CuZnAl shape memory alloy was applied to vibration control of frame structure.Module parameters were modified through calculated frame damp ratio and simulated frame vibration by Simulink of Matlab.And the simulating results of frame vibration coincided satisfyingly with the practically measured curves.The models of seismic wave and wind load were established and added into the computational model of frame vibration as exterior load.
