Research on Dynamics of Four-Bar Linkage with Clearances at Turning Pairs : 2nd Report, Analysis of Crank-Lever Mechanism with Clearance at Joint of Crank and Coupler Using Continuous Contact Model

The method employing the continuous contact model is adapted for analysing the dynamics of the crank-lever mechanism with a clearance at the joint of coupler and lever. Results of numerical calculation of the link motions, the input torque and experimental results for the input torque are shown. They are compaired with the results on the mechanism with a clearance at the joint of crank and coupler in the 2nd report, and the effects of the amount of the variations of clearance, driving speed and mass ratio of coupler and lever on the input torque are discussed for the design of linkage.
