摘要：

Here, in order to study dynamic characteristics of a mechanism system containing clearance of cylindrical pair, a contact force model in cylindrical pair simultaneously considering contact types, material properties, coating material and thickness was proposed. Based on Winkler elastic foundation model and Hertz elliptic pressure distribution assumption, the equivalent elastic modulus of two elastic layers was introduced into the contact force model, and advantages of the proposed contact force model compared with the common conformal contact force model were analyzed in detail. Taking a crank-slider mechanism with clearance as an example, dynamic effects of variation of clearance, driving speed, coating material and thickness on the output component were contrastively analyzed. Some results were compared with the test results published in literature, and the correctness of the proposed contact force model was verified. © 2021, Editorial Office of Journal of Vibration and Shock.
