초록

The vibration of wheel is mainly affected by a fault on a wheel contacting with railway when average speed is over 60km/h. When the wheel vibration caused by wheel scratch increase more than a certain criterion, the wheel is shaved to reduce the vibration. This criterion of shaving is determined from the acceleration signal measured from the sensor mounted on the railway. In this study, vibration characteristics of the rolling wheels having a fault is analyzed with experimental approach to verify the acceleration criterion for shaving wheel.
