Hinge in mechanical systems exist small clearance and contact deformation  After consideration of flexible components  cause the system to the wear and tear  impact force reduced at the clearance  noise  contact time increased  vibration  contact-impact areas expand and clearance also caused disturbance of the rod angular velocity of the linkage. 2011 IEEE.  reliability reduce or even failure[1]. Therefore  the hinge clearance and the impact of flexible components in kinetic models should be considered. In this paper  a nonlinear spring-damper hinge clearance model is considered to establish mechanical system structure of dynamic equations[46]  through a four-bar linkage hinge with multi-clearance rotation of ADAMS dynamic simulation for dynamics simulation study. Simulation results show that hinge clearance and link flexible in Four-link mechanism dynamics have a great impact on performance: connection with the clearance lead to pin holes to produce a series of collisions  and a larger initial impact force
