The effects of several major preparation parameters and temperature on the static compression properties of metal rubber are analyzed, and the mesomechanical model of metal rubber is derived by using cantilever beam element. After a large number of experiments, combining with the least squares method, the parameters of the mesoscopic model are fitted, and the expression of the model including preparation parameters and working temperatures is obtained. Comparing model results with test results, it is found that the accuracy of the theoretical model is high and the model can comprehensively describe the stiffness of metal rubbers. It provides a theoretical reference for the practical application of metal rubbers.
