A Dynamic Analysis of Mechanisms with Clearances

Abstract

The equations of motion of arbitrary moving links and the constraint equations of pairs have been generally derived with consideration of the elastic deformations of pairing elements and frictions, which make it possible to construct systematically the equations of motion of plane multilink mechanisms with clearances. The dynamic characteristics of a slider-crank mechanism with a clearance have been theoretically and experimentally analyzed, revealing the influences of the clearance and the crank speed upon the relative motions between the pairing elements, input torque and output displacement.
