Wheel/Rail Force Prediction and Measurement for Three Transit Trucks Operating at PATCO (Port Authority Transit Corporation)

摘要

Wheel/rail curving force predictions and measurements were made for three different transit truck configurations operating at PATCO. The measured wheel/rail force data showed that both the lateral and vertical forces oscillate between peaks and valleys and at various frequencies. Using a modified friction versus creepage characteristic at the wheel/rail contact patch, the Budd computer model was able to simulate to some degree the lateral force oscillations.
