Abstract
One modeling method of incomplete constraint magnetic levitation system (ICMLS) is investigated in this paper. ANSYS-based simulation of edge effect of an electromagnet is carried out to study on the mechanical properties of electromagnetic force induced by the edge effect, and from the analysis of simulation results, conclusions can be drawn that the edge effect of an electromagnet should not be ignored in the direction of incomplete constraint degree of freedom (DOF) in the ICMLS, and furthermore, a modeling law of the ICMLS is presented. By experiments conducted in the ICMLS prototype, the mathematical dynamics model is developed, and mechanical properties of the prototype is measured in some specified directions of incomplete constraint DOF and damping term is added in the equation of motion. Finally, the proposed modeling method of the ICMLS prototype is validated by some excitation tests and has references for other similar magnetic levitation systems.
