| Abstract: | The thermodynamic characteristics of shape memory effect and pseudoelasticity of shape memory alloys are analyzed; and thermodynamic equation of shape memory alloy energy-dissipation device is founded according to thermodynamic constitutive relation; making use of MATLAB emulator, numerical calculation of practical energy-dissipation damper is carried through. Results indicate that the shape memory alloys provide with evident damping characteristics, it adapts to make structure vibration control damper. |
