PREDICTING THE LOAD ENVIRONMENT ON RAILROAD TRACK

A key factor in all aspects of rail vehicle and track performance, particularly the reliability of the rail and wheel, is the characterization of the wheel/rail load environment. In the context of flaw growth and component fatigue, this characterization is best defined in a statistical sense. Extensive measurements of loads from both wayside and on-board instrumentation during experiments conducted in 1978 on the Union Pacific Railroad have resulted in a substantial "data bank." In this paper, some results from a statistical analysis of these data are presented; and techniques for predicting extreme-value loads and for extrapolating the load environment to other track, traffic, and operating conditions are described.
