RISOverturning and Equilibrium Speeds and Speed Safety Margin—A Sensitivity Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two critical speeds viz., the equilibrium speed and the overturning speed, are recognized to play an important role in defining operational and safety characteristics of railroads. An analysis ...
Wheel-Rail Contact Wear, Work, and Lateral Force for Zero Angle of Attack—A Laboratory Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Most of the wear indices, used in the railroad industry for predicting wheel/rail wear, are functions of angle of attack between wheel and rail. Further, the wear problem has been studied in ...
Influence of Car Tonnage and Wheel Adhesion on Rail and Wheel Wear: A Laboratory Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents the results and analysis of a laboratory investigation, of rail and wheel wear under clean and dry tangent track conditions, utilizing the IIT-GMEMD quarter scale simulation ...
Wheel-Rail Wear and Adhesion With and Without Sand for a North American Locomotive
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A systematic laboratory investigation, of the effect of sanding on wheel/rail wear and adhesion, is reported. The tests were conducted on the IIT-GMEMD Wheel Rail Simulation Facility, using ...
