| Abstract: | The mathematical model of the shrink pseudoelasticity of shape memory alloy (SMA) is investigated. The recovery of vibration reduction element made of SMA is described by means of the first-order differential equation. The model can describe different force-deformation relation by adjusting the parameters. Basing on this model, the vibration response of the vibration reduction system composed of a SMA spring and a mass is analyzed for different excitation conditions. The result shows that the mathematical model is not only simple, practical, universally applicable, but also can well describe the character of this kind of nonlinear vibration system. And this vibration reduction system is more effective in absorbing relatively intensive vibration. |
