Metal rubber is made of metal wire, which is similar to rubber in elasticity and porosity. It has been widely used in aerospace, defense weapons and equipment, modern industry and other fields. In this paper, relevant experiments are carried out on the dynamic performance of the metal rubber damping pad. From the design of the corresponding experimental scheme to the specific analysis of the influence of various material parameters and load forms, the factors that affect the damping coefficient and the relevant laws are obtained. In the experiment, the influences of material parameters including relative density, wire diameter, and loading parameters including amplitude and frequency on deformation response and damping coefficient were explored.
