( College of Architecture Engineering, Liaoning Technical University, Fuxin 123000, China)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.
