Metal rubber-spring isolator is widely used in engineering. To describe the deformation process of the isolator, a mathematical model of hysteresis loop is developed. The hysteresis loop for any loading or unloading process can be obtained by transforming the primary loading line and the hysteresis loop in one cycle, and the performance of the isolator can be analyzed with these loops. The comparison of theoretical results with experimental results shows that they are in good agreement.
