Experiments were performed to study the effect of varies excitation level relative density and material properties on the vibration characteristics of Metal Rubber (MR).Some general disciplinarians of characteristics of MR were found.Based on non-rigidity and non-damping

the method of describing vibration performance of MR was presented

steady response was calculated

and the results were contrast to testing results.The results show that the large the vibration intensity

the better the damping effet will be.
