Abstract: In this paper, taking the multi-link driving mechanism of a high-speed precision press as the research object, the corresponding kinematics equations are deduced. At the same time, kinematics analysis is performed by using MATLAB software to obtain the motion law of the slider, and the advantage of this mechanism is proposed in comparison with the crank slider mechanism. Then, based on ADAMS software, the parametric model of the driving mechanism is established and simulated. By comparing the simulation data of being imported into MATLAB with the derived formula, the correctness of the parametric model is verified. In addition, by analyzing the influence of the length change of each rod on the stamping slider and the mechanical pressure angle, the multi-objective optimization of the mechanism is carried out, which provides reference for the optimization design of homogeneous mechanisms.
