  • To solve the issue of frame lateral instability alarm of high-speed EMU (electric multiple units) in the running process, a vehicle dynamics model considering hollow worn tread was established. The wheel-rail relationship between worn treads of different running distance and rail as well as the influence of hollow worn tread on vehicle stability were researched used theoretical analysis, simulation analysis and field tests.The calculation results show that the contact points between turning tread and rail are in uniform distribution. However, for hollow wear tread, contact points distributed on both sides of the depression area. The“False flange effect”initiated by leap metastases of contact point caused severe lateral wheel/rail impact. While the vehicle running at high speed, the lateral vibration frequency is close to the natural vibration frequency of the frame itself, which would induce lateral coupled vibration of bogie and exceed the limit criteria. Through simulation analysis and field test discover hollow worn tread is an important indication for frame lateral alarm. Using wheel re-profiling can improve lateral stability of bogie.
