Displacement analysis of slider in slider-crank mechanism with joint clearance

Abstract

ABSTRACT Joint clearances need to be specified for the assembly and operation of mechanisms. When the joint clearances are determined while designing, it ensures the robust operation of the mechanism. The robustly designed mechanisms perform the specified tasks with the least deviation. The validation of such robustly designed mechanisms by fabricating experimental setup is a difficult task. Simulated analysis of the parametric model of such robustly designed mechanisms can be done using suitable software. In this paper, the effect of joint clearances on the displacement of the slider in a slider-crank mechanism has been discussed. A slider-crank mechanism with adjustable joint clearances at both ends of the connecting rod has been designed. Three pin pairs have been designed for generating adjustable joint clearances. Two models of the slider-drank mechanism have been developed in ADAMS/View. The first one has been without joint clearances and the second one has been with adjustable joint clearances. The simulated results of without clearance model validate the slider displacement at ideal conditions. The simulated results of the adjustable joint clearance model have been experimentally validated using an experimental setup.
