Abstract: Importance of the wheel rail contact stresses in track degradation and safety of trains is discussed. Theroetical elastic contact stresses based on Hertz theory for various U.S. railroad cars ...

Abstract: An experimental study of the real contact stresses for U.S. locomotives and rails including the effects of plasticity and wear has been performed under laboratory Hertzian simulation using the ...

Abstract: The Vibration Test Unit (VTU) of the Rail Dynamics Laboratory at Pueblo, Colorado, can be used for vibration testing of railroad vehicles with revenue track input. Until recently, the usual ...
