Abstract: The study established the dynamic model of rotor system of vertical axis magnetic levitation wind turbine based on the rotor dynamics theory.The finite element model of the bearing-spindle-thrust plate of vertical axis magnetic levitation wind turbine system was established built by ANSYS Workbench finite element analysis software.To study the influence of the position of the auxiliary bearing on the critical speed of the vertical axis rotor system through modal analysis method and drew a conclusion that the change of the auxiliary bearing position and the critical speed of the vertical axis rotor system.The research results provide a theoretical basis for the structural design,installation and as maintenance of the vertical axis magnetic levitation auxiliary supporting device.

Key words: auxiliary bearing position, magnetic suspension wind, critical speed, Workbench
