Simulation and Experimental Validation of Slider Displacement in Slider Crank Mechanism with Connecting Rod Tolerance and Joint Clearance

In this paper, a simulated analysis and an experimental validation of slider displacement in a slider crank mechanism have been done. Link tolerance and joint clearance have been considered for the analysis since these factors influence robustness of mechanism. A slider crank mechanism has been designed by specifying tolerance of connecting rod and joint clearances at slider-connecting rod and crank–connecting rod joints. Slider displacement simulations have been performed using ADAMS/View software. In order to understand the effect of speed on slider displacement, simulations have been performed at three crank speeds. All simulation results have been validated by performing experiments on the fabricated setup. It has also been observed that the joint clearance influenced variation in slider displacement is higher than the link tolerance and the speed variation. Thus, the robustly designed mechanism could be analyzed by simulating in ADAMS/View by varying the design parameters within specified ranges than by performing experimentation on fabricated setup.
