Analysis and research on the track beam of normal conducting high-speed maglev
Based on the characteristics of the normal conducting high-speed maglev transportation system,the vibration model of the interaction between maglev vehicle load and track beam is established by comparing the characteristics of different track beam structures,and the vibration characteristics of track beam under different operating conditions are revealed through model analysis.The research found that different track beam structures should be optimized and adapted for different operation scenarios to improve the system performance.The vehicle load-track beam model constructed in this article could effectively capture the main characteristics and vibration principles of the vibration of track beam.Further analysis points out that factors such as vehicle moving speed,system damping,vehicle length,and the fundamental frequency ratio between bridge and moving load have certain significant effects on track vibration.This research could provide an important theoretical basis and reference for the design and optimization of normal conducting high-speed maglev track beams in the future.
