N2 - To address the issue that the dynamic characteristics of the rotor of the high-speed magnetic levitation molecular pump are difficult to calculate and analyze, a simplified modeling method for the rotor assembly based on the equivalent mass-stiffness theory is proposed. An equivalent solid rotor model with multi-segment variable cross-sectional characteristics is constructed. By comparing the simulation results of the finite element simulation analysis software with the experimental values, the feasibility and effectiveness of the equivalent model are verified, and it provides guidance for the design of the rotor.
