Dynamics of the bogie of a maglev system with guideway irregularities

This paper describes the stability of a bogie in the electrodynamic suspension system with superconducting magnets, especially in response to displacement of the levitation coils. The result of dynamic analysis indicates its stability with the displacement of coils which may happen most frequently; such as a longitudinal displacement and a vertical displacement. In addition, Cayley-Klein parameters are adopted for conversion of coordinates in this analysis in order to simplify it instead of Euler angles which are usually used in 3-dimensional analysis. All simulations in this paper are conducted with these parameters.
