Summary
Short-pitch rail corrugations with wavelength of 30-40 mm have been found in straight and curved tracks in a Guangzhou metro line. The failures of coil springs of primary suspension of vehicle and rail fastener clips are closely related to the shortpitch rail corrugation. Vibration accelerations of vehicle and track components were measured simultaneously in the corrugated tracks. Accelerations of railheads, rail fastener clips, axle boxes and bogie frames are very sensitive to the short-pitch rail corrugation. Vibration characteristics induced by the rail corrugation with the passing frequency of about 625-833 Hz have been found in the components of both track and vehicle. High-frequency vibrations of the components can be eliminated after rail grinding.
