Description
Summary:A three-dimensional running simulation program of the train motion which includes both electromagnetic and mechanical systems has been developed. For verification of running stability, the motion of the Maglev train with four bogies and three cars running into the curved section was calculated. Because the spring strength of the secondary suspension between bogies and cabins was much smaller than that of the electrodynamic suspension, interaction among bogies was small. The lateral displacement reached 0.045 m, which is about 50% of the lateral air gap. Therefore, the train can run without touching the wall of the guideway. As this lateral air gap caused roll torque, total roll angle of the bogie became 12.5% larger than the cant angle of the curved section.
