Abstract/Summary High impact forces arising from wheel impacts can damage train and track components. Early detection of wheel defects which causes these high impact forces is needed to prevent catastrophic failure of these components. The accelerometer based methods for determining the wheel impact load resulting from wheel defect is commonly used in Australia. This method relies on the dynamic response of the track in determining the magnitude of the impact load imposed on the track by a defective wheel. This study compares the rail acceleration due to dynamic impact forces caused by wheelflat for different axle load, wheel mass and train velocity. It is found that similar rail acceleration can be brought about with dynamic contact force that differs significantly for different axle load. It is also found that for high axle load the rail acceleration spectrum is concentrated in the lowe r frequency region.
