In order to choose the reasonable application environment of shape memory alloy damper, the influences of environment parameters such as temperature and amplitude of excitation on vibration reduction characteristics of the shape memory alloy damper are investigated. The dynamic equation of the vibration system is firstly established as the bilinear model is adopted to describe the superealsticity of SMA, and then transform the equation into the dimensionless one. Subsequently, the primary resonance amplitude-frequency response equation of the dynamic system is acquired by the average method, and the accuracy of the one is confirmed by the numerical method. Finally, the concepts of resonance amplitude ratio and resonance frequency ratio between the system with SMA damper and the corresponding linearization system are defined to express respectively the effects of vibration reduction and frequency tuning of SMA damper, and the relationships between the environment parameters and the effects are studied. The results suggest that the vibration reduction effect will be weaken as the temperature increasing, and the SMA damper will work well in a certain range of excitation amplitude. The results will give the guide to choose the application environment for the SMA damper.
