Abstract

Abstract: The physical model, mathematical model and simulation model of the magnetic levitation system were set up. The function among magnetic force, electromagnet current and distance was deduced after the measuring. The dynamic equation of magnetic levitation ball was derived. The simulation model of the magnetic levitation ball system was set up. The simulation experiments for no vibration and external vibration and chaos state of the system were conducted. The phase trajectories of stable, quasi-periodic and chaotic states were researched. The waveforms of no vibration and external vibration and chaos state were measured. The tests show that the measured waveforms are same as simulation waveforms. Using the established model, the stability of the magnetic levitation ball system impacted by various system parameters and acquire optimal parameters of the system could be understood. The chaotic characteristics of the magnetic levitation system could be understood further completing the data processing of the system.

Key words: magnetic levitation, initial state, dynamic equation, simulation model
