Abstract：

The linear die library system of CNC punching center was designed, and its three-dimensional model was established by Creo 3.0. Thus, the working principle of the die library system was analyzed. The modal analysis of die library system was carried out by ANSYS Workbench, and the top six order natural frequency and vibration mode were obtained. Furthermore, the accuracy of the modal analysis was verified by experiment. The results show that the working frequency is lower than its inherent frequency range, so the resonance will not occur. Through the analysis of the transient dynamics analysis, it is concluded that the maximum equivalent stress is up to 8.3024 MPa when t=0.16 s and it is far less than the material yield strength 355 MPa. So the design of die library system is reasonable, and it can meet the strength requirement under the impact loading.
