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.
