Keywords: Roller Rig, Wheel-Rail Contact Mechanics, Rail Vehicle Dynamics, Contact Patch Dynamics, Wheel Forces and Moments
Abstract: A need exists for a new test rig design with advanced sensing technologies that will allow the railroad industry and regulatory agencies to better understand the wheel-rail...
Keywords: Plastic tie, composite tie, tie insertion, tie nipping, bending loads
Abstract: Damage to plastic composite ties during handling and track installation has been reported by a number of railroads. Results from a survey conducted to identify specific handling...
Keywords: Strain levels, joint bar fatigue analysis, residual stress, joint bar strength
Abstract: Detailed analysis of measured bending strains shows that the foundation deflections have the most significant effect on the magnitude of strains. All other factors, such as track...
