Ems Maglev Train Solenoid System Suspension And Traction Mechanism Of The Numerical Analysis

The numerical techniques for simulating the transient behaviors of a maglev train are studied in this thesis. To this end, the magnetic suspension technology and its successful application on the magnetic levitation vehicle is briefly summarized. The details about the development of the mathematical model and method of the time steeping finite element method coupling with the external circuit model are then followed. To avoid the mesh distortion in the airgap arising from the relative movement between the stator and rotor, the moving boundaries are incorporated into the finite element model. Therefore, the movement effect of the train as well as the saturation of iron materials are considered properly. To valid the proposed model and method, the no-load levitation force of a model Maglev train is calculated and the numerical results shown good agreements with the measured ones. Based on those works, the transient propellant and levitation forces of the Maglev train are investigated extensively using the proposed model and methods, and some suggestions for engineering applications are proposed, which may be valuable for the analysis of maglev vehicles in Shanghai, China.
