    Abstract:

    In this paper, against the background of the research on the performance of dampers for a certain type of spacecraft, a new type of shape memory alloy metal rubber (SMA-MR) which was made of Ni-Ti alloy wire processed by coil spring ,cold stamping and post-treatment damper is designed. Through theoretical and experimental research on SMA-MR dampers, the equivalent rigidity and energy dissipation coefficient of the damping system at different temperatures are analyzed. The law of mechanical properties of SMA-MR material with temperature is studied. Using the experimental results to analyze the relationship between equivalent rigidity, energy dissipation coefficient and temperature. The research results show that the mechanical and damping properties of SMA-MR dampers are subject to certain regularity due to temperature. The analysis results provide theoretical basis and data reference for the design of SMA-MR dampers and their application under extreme environment.
