Abstract: The two revolute pair clearances in the crank slider mechanism are considered. The mathematical model which describes the revolute pair clearances is introduced. A modified hybrid nonlinear spring damping collision force model is used to analyze the collision characteristics of revolute pair. The dynamics model for crank slider mechanism with two revolute pair clearance is established by using Newton Euler's method. Finally,the simulation of velocity,acceleration and contact force are developed with respect to the different values of the pair clearances. The results show that the magnitude of the pair clearance is an important element to influence the dynamic characteristic.
