In this investigation, the effect of revolute joints’ clearance on the dynamic performance of mechanical systems is reported. A computation algorithm is developed with the aid of SolidWorks/CosmosMotion software package. A slider-crank mechanism with one and two clearance-joints is studied and analyzed when working in vertical and in horizontal planes. The simulation results point out that the presence of such clearance in the joints of the system understudy leads to high peaks in the characteristic curves of its kinematic and dynamic performance. For a multiclearance joints mechanism, the maximum impact force at its joints takes its highest value at the nearest joint to the input link. This study also shows that, when the mechanism works in horizontal plane, the rate of impacts at each clearance-joint increases and consequently the clearance-joints and actuators will deteriorate faster.

Kinematic Properties

A method for designing a mechanism which is free of contact loss in clearance connections is developed. Only revolute joints are considered as possible clearance joints. Earles and Wu's empirical formula has been used for defining a perfect joint or contact loss free joint. A general theory for conditions of a perfect joint has been derived in terms of the mechanical energy and the kinematic properties of the joint. This general theory was applied to a slider crank mechanism and it was shown that designing a perfect joint is theoretically possible through balancing by a non-linear spring. Further it was shown that this technique gives a practical guide for balancing a mechanism with linear springs to reduce the possibility of contact loss in clearance joints.
