Experimental Investigation on Durability of A Combined Rotor Bearing Support with Metal Rubber Material under Dynamic Loadings

摘要

Durability of a combined rotor bearing support with Metal Rubber(MR) material under dynamic loadings was tested in order to provide the information about life and durability for the application of MR material in engineering. Based on the experiments on the rotordynamic properties of a rotor system with the combined bearing support and quasi-static test on the hysteresis properties of the combined bearing support, it can be concluded that the combined bearing support could provide stable stiffness and damping to the rotor system, with a maximum excitation of 1.17×10~7 times which could meet the requirements of durability in engineering.
