The Calculation of the Centripetal Force of a Magnetic Suspension System using ANSYS

摘要

The centripetal force of a magnetic suspension disc is compared by experimental results, calculating by use ANSYS and calculating by Force-Balance method. Research results show that centripetal force of a magnetic suspension system is related to the structure and control system. For the control currents of the magnetic suspension disc are not known in advance, thus it is impossible to directly adopt ANSYS to calculate centripetal force, the control currents of the magnetic suspended disc measured by experiments is used to form ANSYS calculation model. The calculate results using ANSYS match well with the experimental measurements. The calculation of Force-Balance method is not applicable to calculate centripetal force of the magnetic suspension system. The process of the calculation is introduced and the error in the calculation is analyzed as well.
