Lateral Dynamic Performance of High-Temperature Superconducting Pinning Maglev Vehicle Driven by Electrodynamic Wheel at Medium and Low Speed

High-temperature superconducting (HTS) pinning Maglev has the advantages of self-stationarity, low noise, and resistance. This technology can be applied in urban rail transit, such as straddle-type monorail vehicles. Due to the limited space for placing the drive device above the track, electrodynamic wheel (EDW) drive can be applied effectively utilizing the ample space on both sides of the track, realizing contactless drive. In this article, the lateral dynamic performance of an HTS pinning Maglev vehicle driven by EDW is analyzed. Initially, two-dimensional transient simulations under various rotational speeds of the EDW are conducted. The influence of different working air gaps on the device's normal force and propulsion force is analyzed. Subsequently, a dynamic model of HTS pinning Maglev vehicle with EDW is established. EDW's influence on the lateral dynamic performance of HTS pinning Maglev vehicle is analyzed, and the lateral dynamic performance of the vehicle at various speeds is simulated. The results show that the HTS pinning Maglev vehicle driven by EDW has good lateral dynamic performance in the low and medium speed range, and EDW can effectively improve the lateral stationarity of HTS pinning Maglev vehicle. This article can provide a new driving mode for HTS pinning Maglev vehicle and reference for improving and optimizing the existing medium and low speed straddle-type monorail vehicles with HTS Maglev technology.
