Research on Dynamics of Four-Bar Linkage with Clearances at Turning Pairs : 4th Report, Forces Acting at Joints of Crank-Lever Mechanism

抄録

The forces acting at the joints of a crank-lever mechanism with a clearance at turning pairs are found by a straightforward solution of the equations of motion of the moving links. In each case of the mechanism with a clearance at the joint of crank-coupler or coupler-lever, the forces acting at the joints are calculated by the kinematic analysis in 2nd and 3rd reports. The following points are discussed: (1) a shaking force acting on the frame, (2) effects of the amounts of clearance, driving speed and mass of link on the forces acting at the joints, and (3) comparison of the direction of a force acting at the joint with the contact angle and the limits of applicability of the continuous contact model.
