Abstract

In this paper, the wavelet transform-based approach is studied to analyze the transient oscillatory response of an electrodynamics suspension (EDS) maglev system. The magnetic field intensity is mainly a function of the levitation height between the cradle and the track. The wavelet transform-based approach is used to analyze the harmonics of the magnetization function. Haar wavelet is selected as the mother wavelet to decompose the coefficients of the wavelet transform. Field analyses based on the Fourier series and the finite-element method are provided in order to illustrate the advantage of the proposed scheme in the analysis of dynamic characteristics of the beginning stage of levitation
