Popis: The sealing machine is the key part of the copper pen tip processing machine, and its working stability will have a direct impact on the processing quality of the pen tip. Taking copper pen tip desktop processing equipment for an example, to improve the quality of pen tip, the modal analysis was carried out on the system by large-scale finite element analysis software ANSYS. The modal parameters of the rotor system were calculated, and through the Campbell diagram, the critical speeds of the system were obtained. Finally, the critical speed under different structural parameters is obtained. By analyzing data, the critical speed of the system is negatively correlated with the bearing spacing, and positively correlated with the diameter of the long shaft section, and independent of the bearing stiffness. The analysis results provide a theoretical basis for the optimization design of structural parameters of the system and the design of the maximum working speed, which also has certain reference value for the research and design of copper pen tip desktop processing equipment in China.
