【Abstract】 This paper presented a theoretical model of loss factor of metal-rubber.Dynamic experiments on a metal-rubber structure were made.Effects of the material density and the heat treatment technology on the loss factors of the structure were investigated qualitatively,and effects of the heights of the material and the weights of the system on the loss factors were also studied quantitatively.The relation between the two parameters and the loss factor was obtained by the least square method.The loss factor of the structure was predicted,and the result established a theoretical foundation for analysis of dynamic response of metal-rubber.更多还原
