[摘要] 综合利用不同的耗能机理共同耗能和具有多道耗能减震防线的阻尼器是目前阻尼器设计的新思想。针对以往液体粘滞阻尼器的不足，为了获得性能更优异的阻尼器，在普通液体粘滞阻尼器研究的基础上，利用形状记忆合金( SMA)的超弹性性能，设计出一种新型SMA绞线一液体粘滞阻尼器。首先进行了SMA绞线的力学性能试验，分析其超弹性性能，然后分析该阻尼器的工作原理及SMA绞线和液体粘滞阻尼器共同耗能的工作机理。最后数值分析计算了这种阻尼器在不同工况下的阻尼力．位移曲线，通过与普通液体粘滞阻尼器对比分析，验证所研制的SMA绞线一液体粘滞阻尼器具有更优异的性能。

Abstract: It is the new idea of damper design to use dampers with different energy dissipation mechanism comprehensively to dissipate energy and the dampers with more damping line of defense. For the deficiencies of the fluid viscous damper, in order to obtain the damper with better performance, on the basis of normal fluid viscous damper research,a new type of SMA wires-Fluid Viscous Damper using the super-elasticity of SMA was designed. Firstly, mecharucal experiment of SMA wires was made, and its super-elasticity properties were analyzed. Then the working principle of the damper and the working mechanism of SMA wires and fluid viscous damper dissipate energy together were analyzed. Finally, through the numerical analysis and calculation of such a damper in different conditions of damping force-displacement curve, contrast with the fluid viscous damper, it was verified that the SMA wires-Fluid Viscous Damper has more excellent performance.
