【Abstract】 The steady-state responses and slip reliability of sliding systems with hardening restoring force,to Gaussian white noises,are predicted analytically in this paper.Based on the equivalent linearization of friction damps,the probability distribution of the steady-state responses are obtained;The approximate analytic solution of slip reliability are given in accordance with a first-passage failure problem.On the basis,the optimum designs of sliding systems can be further conducted.更多还原
