The initiation and evolution of short-pitch corrugation in Beijing metro line 4 was studied from the viewpoint ofwheelset vibration. A three-dimensional elastic model was set up. Numerical simulations were undertaken with this model to analyze the corrugation by the wheelset vertical vibration and torsional vibration. Based on numerical results, the relation between rail corrugation and wheelset vibration, and the relation between the position of electromotor and wheelset vibration were indicated. It is found that avoiding the wheelset-rail resonance is one method of controlling the rail short-pitch corrugation and solving the vibration and noise problem in metro lines.
