In the actual work of hydraulic press, in order to ensure the design of auxiliary punching structure, that is, swing punching structure runs smoothly, the modal analysis of swing punching structure is carried out by using ANSYS software. The first 40 natural frequencies are determined, and the first 10 modes are analyzed. The shape variables and deformation modes are determined. Thus, the actual vibration response of the structure under the action of various external or internal vibration sources in each frequency band can be predicted to avoid resonance phenomenon in the work. At last, the aim of safety production, material saving and cost reduction is achieved.
