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
Experimental study on a general data-based nonlinear identification approach for a MDOF frame model structure.
