摘要：
In order to comprehensively analyze the influence mechanism of track irregularity and wheel-rail profile compatibility on metro vehicle sway, a combination of dynamic test and numerical simulation was used to study. The lateral vibration acceleration of swaying vehicle, wheel-rail profile and track irregularity were tested. The characteristics of vehicle sway and differences in wheel-rail profile compatibility were revealed. The influence of track irregularity and wheel-rail profile compatibility on vehicle sway were analyzed. Results show that the ride quality will be seriously affected when there is periodic irregularity on the metro operation lines. The difference in the proximity of bogie hunting frequency due to wheel-rail profile compatibility, track excitation frequency and carbody sway modal frequency is the cause of the difference of vehicle ride quality. Measures should be taken in time to treat periodic irregularities on the lines. Meanwhile, reasonable control of the equivalent conicity of wheel-rail profile compatibility can effectively improve the running quality of metro vehicle. © 2022 Zhejiang University.
