Keywords: Friction, friction management, lubrication, vehicle-track interaction, wheel-rail interaction v
Abstract: Friction has a huge influence on the vehicle/track interaction and yet it remains poorly understood, its consideration an afterthought in many simulation activities. This survey...
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: LIDAR, noncontact velocity measurement, curvature, alignment, ATGMS, track geometry, Railway Technologies Laboratory, Virginia Tech
Abstract: The results of an extensive series of tests are presented to evaluate the viability and applicability of LIDAR systems for measuring track speed, distance, and curvature in...
Keywords: Rail base corrosion, corrosion, corrosion treatments, fatigue, rail life
Abstract: Rail base corrosion combined with fatigue or damage can significantly reduce rail life. Studies were done to examine the relative contribution of damage, corrosion, and fatigue on...
