Abstract�� According to problems of the high mode density of natural frequencies of plane-shell structure and a broad spectrum of aerodynamic excitation forces, a new metal rubber (MR) component was designed by improving the processing technology of MR. It is called metal rubber particles (MRP). The WDW3100 electronic universal testing equipment was used to obtain static characteristics of MRP damper experimentally. The average stiffness and loss factor of MRP was obtained by measured the static hysteresis loop. The material parameters and process parameters on the influence of stiffness and damping characteristics was obtained by experimental results. Through this study, it provids experimental basis for further research and engineering application of metal rubber particles damper.
Keywords�� metal rubber particles   static characteristics   nonlinear stiffness   hysteresis curve
