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
