Abstract：

Based on the non-parametric rigid body contact-separation clearance analysis model of revolute pair, for the revolute pair with the large amount of clearance change and the most sensitive to the change of balance force, the optimum balance force required for 200 kN compact press was studied, and the evaluation indicators of clearance change were given from four aspects such as the angular displacement of clearance, the angular velocity of clearance, the motion error of slider and the collision force of clearance to determine the optimal balance force required by the press. Then, the changes of the four clearance evaluation indicators were analyzed by applying different balance forces on the slider, and the optimum balance force applied to the slider of press was determined. Finally, the Adams simulation was used to verify that it is reasonable and feasible to predict the optimal balance force of press with the clearance model for the deep drawing press with offset six-bar linkage mechanism.
