In order to study the dynamic characteristic of mechanism with joint clearance, an improved hybrid contact model in the joint clearance is established. The friction effect is considered by using improved Coulomb friction model. Then the hybrid contact model in joint clearance is incorporated into ADAMS. For the crank follower mechanism, the dynamic model of mechanism with joint clearance is established and the dynamic simulation is carried out. The simulation results can predict the effects of clearance on the mechanism dynamic characteristic preferably, and which is the basis of mechanism design. The contact hybrid model for clearance in this paper develops the contact modeling of clearance and dynamic characteristics analysis of mechanism with joint clearance, and it is useful for engineering application.
