Dynamic Analysis of Super-Speed Maglev Train-Guideway Interaction System

초록

Dynamic responses of a super-speed maglev train-guideway interaction system including a control algorithm are rigorously investigated. The train is represented by a mass-damper-spring system which is levitated electro-magnetically. The guideway is modeled by a three-dimensional frame structure. The electromagnetic forces between the train and guideway are assumed to have small fluctuations from their static values and linearized with respect to the values. In order to control air gaps for levitation, the active control algorithm is employed. Dynamic governing equations for the maglev train-guideway interaction system including the control algorithm are derived. A solution of the governing equations is obtained iteratively. Using the developed method, dynamic responses of a super-speed maglev train-guideway interaction system are examined.
