Abstract：

Body vibration is the key factor affecting the precision, life and product quality of press. So the analysis on the influence of eccentric gears on the vibration of press has been paid more and more attention. The three-dimensional model was established based on the structure of a press，and the static analysis according to the actual working status of press was conducted by finite element analysis software. Then, the equivalent stiffness of press was obtained by integrating the deformation of each part, and a vibration model was set up under the condition of press idling. Furthermore, the corresponding calculation method was put forward, and the change relationships between the natural frequency and amplitude and the eccentric gear rotation angular velocity were obtained to avoid the resonance phenomenon of press. On the basis of theoretical calculation, further testing and data analysis, the change relationships among eccentricity，quality and amplitude of eccentric gear were obtained under the given speed to provide a reasonable optimization scheme for the vibration design of press idling.
