Error Analysis of Four Bar Planar Mechanism Considering Clearance Between Crank & Coupler

A. M. Vaidya and P. M. Padole

ABSTRACT: Joint clearance leads to mechanical error in mechanism. The problem has been addressed by a number of authors, who have analyzed clearance effect from different perspective. In this paper exact location of clearance link has been identified using dynamic analysis. Mechanical error in coupler point and output angle deviation due to clearance link and its exact location is dealt using sensitivity linkage and velocity analysis.
