In order to reflect the incremental cumulative damage degree of metal rubber, the stiffness damage and damping damage are used to accurately describe the fatigue damage process of metal robber, and the comprehensive damage factor is proposed to be the fatigue failure criterion. Additionally, the nonlinear excitation effects on dynamic stiffness and damping of a filled rubber isolator are investigated. It is difficult to describe damage evolution of metal rubber in the microscopic perspective, and from a macro point of view, it is feasible method to describe degree of fatigue damage which bases on the changes of mechanical properties. The damage of metal rubber which is accumulated with its inner partial broken and wore wires, results in deterioration of its macro-mechanical characteristic, macro-cracking and final fatigue failure, so it does not rupture as sudden failure of solid material.

The fatigue damage test of metal rubber vibration isolator is performed, the result of which shows that fatigue damage performance of metal rubber is different from conventional solid materials.
