Dynamic Analysis of Wheel-Type Train Propelled by Superconducting Linear Synchronous Motor

초록

This study deals with the dynamic analysis of 600km/h wheel-type train propelled by superconducting linear synchronous motor(LSM). This train is of a traditional wheel-on-rail type with traction motors on wheel-bogies. However, for the 600km/h speed, on the both sides of each vehicle, superconducting LSMs are attached and the ground coils are installed on the guideway. In this case, the guideway irregularities act as disturbance to the vehicle causing deterioration of ride comfort. And besides thrust force, the normal force could be created in superconducting LSM control, which influences vehicle dynamic behavior during running. In this study, to examine the effect of guideway irregularity and normal force in wheel-type train propelled by superconducting LSM, the vehicle dynamic model is driven and frequency analysis is performed through simulation.
