Abstract：

For the drive mechanism of the eight-links mechanical press, its parametric entity modeling was established by Solidwords. Then, the dynamics analysis of mechanism was finished by the ANSYS Workbench software, and the motion characteristic curve of the slider in institutions and the load of the component were obtained. Furthermore, the lower link was selected as the research object when the press reached nominal position, and the results from the static analysis show that the maximum stress of lower link were lower than the material allowable stress. The result of fatigue safety factor turned out to be 0.845 after further cyclic loading being added to lower link to conduct fatigue analysis. Based on the optimization goals of the maximum stress lower than the material allowable stress, fatigue safety factor higher than 1 and the lightest mass, the size of the lower link was optimized. Finally, on premise of meeting the strength requirements, the optimization goal of lightweight, low stress and high security were realized with the fatigue safety coefficient 1.15 and mass reduced by 4%.
