The report discusses several studies involving factors that significantly affect rail life, particularly wheel impact loads. Parameters that characterize the effect of wheel impact loads on rail behavior are examined in terms of system variables such as geometry, material properties, loads, and track conditions that affect stresses which in turn control the mechanism, probability, and mode of failure. Quantitative descriptions of wheel/rail load characteristics typically encountered were obtained from a review of the literature and results from recent laboratory and field measurements.
From October 1983 to November 1984, a lubrication study funded -by the Federal Railroad Administration was conducted by the Association of American Ra...
The wheel/rail dynamics interaction project being conducted as part of this program is directed toward reduction of maintenance costs and wheel/rail n...
