In order to describe the deformation process of metal rubber and spring combined vibration isolator, a mathematical model of elastic hysteresis loop of metal rubber and spring combined vibration isolator is established. By transforming the initial loading curve and the elastic hysteresis loop of one cycle, the elastic hysteresis loop can be obtained for any loading and unloading process of the vibration isolator, and then the performance of the vibration isolator can be analyzed by hysteresis loop, Reduce a lot of experimental research work.Comparison of theoretical data and experimental test results show that the experimental data and the theoretical model has a good agreement
