Abstract：

The three-dimensional model was established and a brief introduction of each part was made according to the structure of 500 t straight single point press with combined frame, and the equivalent stiffness of body part and slider was analyzed by using ANSYS finite element software. A simplified vibration model was established according to the press system features, and corresponding vibration calculation method was put forward at the same time. Combining the theoretical analysis，system parameters and the force of the press，the natural frequency was got，and the change of vibration amplitude with excitation frequency was stated. The calculation results show that when the excitation frequency is close to natural frequency, the amplitude of press will be larger, and based on the calculation process, the main structural parameters affecting the press vibration can be got. Comprehensive analysis shows that the designers can make vibration analysis through the main factors affecting the press vibration and make reasonable optimization scheme for vibration reduction.
