Dynamic Characteristic Research of Planar Four-Bar Mechanism with Joint Clearance

Bo Shao, Rui Bin Guo

Abstract

The joint clearance on mechanism dynamic characteristics influence can not be ignored. This paper established a geometrical model of planar four-bar mechanism, it built the model of contact force and friction and embedded into the software of ADAMS dynamics analysis mechanical system, which analysis the dynamics simulation of mechanism. We obtain a accurate prediction of dynamic characteristics of mechanism with joint clearance effect from the analysis. What's more the results provide reference and basis for later mechanism design [1,2,3].
