Abstract
In order to study the dynamic characteristics of mechanisms with revolute clearance joints, an improved nonlinear contact impact face model was established here, the axial dimension was introduced into the model, and the friction force in clearance joints was described using a modified Coulomb friction model. As an example, a slider-crank mechanism was taken as a study object, the two models mentioned above were introduced into the system's dynamic equations. The effects of clearance, driving load and friction coefficient on the dynamic characteristics of the mechanism were analyzed with simulations. The simulated results were compared with those of tests. The results showed that the simulation results agree well with the test ones, the two models can accurately and effectively describe the dynamic characteristics of mechanisms with revolute clearance joints.
