Abstract：Combined with finite element simulation in ANSYS,this paper designed and produced a buffer device based on polyurethane magnetorheological elastomer (MRE). A drop-induced test and a shock response spectrum test were constructed to evaluate the shock response properties of the MRE buffer. The experimental results indicate that the buffer possesses a good attenuation effect,and the cushioning effect increases with the applied magnetic field. This reveals that the cushioning effect of the designed buffer can be controlled by the applied current.
