| Abstract: | The paper studies the formation of short-pitch corrugations on Beijing metro lines from the perspective of wheel set vibration.Based on the resonance of wheel and rail from in-situ investigations and field tests,3-D finite element models of the wheel set were set up.Numerical analysis was carried out to analyze the wheel set vertical vibration and torsional vibration both for the mobile train and for the trailers.Based on the results,the relationship between rail corrugation and wheel set vibration has been... |
