摘要：
A precise tangential contact damping model is proposed, which includes the lateral contact of the upper-lower asperities and the interaction of adjacent asperities. The effects of the normal static preload, frequency, and amplitude of tangential displacement on the tangential contact damping were analyzed by simulation, respectively. Furthermore, the results of simulation are verified by experiment. The tangential contact damping of considering the interaction and lateral contact of asperity is very close to the experimental results.
