AN INVESTIGATION OF IMPACT LOADS DUE TO WHEEL FLATS AND RAIL JOINTS

Vertical impact loads between wheel and rail result from running surface anomalies such as flat spots on a wheel or a dipped rail joint. Recent measurements of loads under high-speed freight traffic have resulted in both a qualitative evaluation and a statistical definition of impact loads. These data have been utilized to develop mathematical models of wheel/rail impact behavior, to define shock loads on truck components as well as loads and stresses in the rail and track structure.
