AbstractThe application of a Monte-Carlo stochastic modeling technique to simulate a loaded coal car fleet running over a sharp curve has successfully reproduced the distributions of wheel/rail forces measured in the field. In the case of lateral force, wheel/rail friction and contact conditions are found to have the highest impact among the many parameters evaluated. For vertical force, the unevenly loaded condition is identified as one of the key factors. To better diagnose truck performance based on wheel/rail force measurements collected by the Truck Performance Detector (TPD), normalization methods to reduce “false alarms” due to non-truck factors such as wheel/rail friction and contact conditions are required.
