Abstract：

In order to reduce the vibration of mechanical press and improve the quality of workpiece, the characteristics of inertia force produced by slider crank mechanism of press were analyzed. And the result shows that the mass of slider is one of the main factors affecting the magnitude of inertia force. Then, with the goal of reducing the mass of slider and the equivalent inertia force, without affecting the strength and stiffness of slider, the topology optimization analysis of the slider was carried out by using the topology optimization module of ANSYS Workbench. And through simulation analysis, it is found that the mass of slider before and after optimization is reduced by 16%, which verifies the feasibility of this method. At the same time, the vibration model of single-degree-of-freedom system for press was established, and taking the vibration response of fuselage as the objective, the vibration response curves of slider before and after the slider topology optimization were analyzed and compared. The results show that the maximum vibration amplitude is reduced by 14.3% before and after the slider topology optimization, which verifies the reliability of the method and provides a certain reference for the vibration reduction of mechanical press.
