State of the Art Roller Rig for Precise Evaluation of Wheel-Rail Contact Mechanics and Dynamics
… development of a state-of-the-art single-wheel roller rig for studying contact mechanics and dynamics in railroad applications. The use of indoor-based simulation tools has become a mainstay in vehicle testing for the automotive and railroad industries. In contrast to field-testing, roller rigs …

Analytical Evaluation of the Accuracy of Roller Rig Data for Studying Creepage in Rail Vehicles
… is to investigate the effectiveness of a scaled roller rig for accurately assessing the contact mechanics and dynamics between a profiled steel wheel and rail, as is commonly used in rail vehicles. The established creep models of Kalker and Johnson and Vermeulen are used to establish correction …

Analytical and experimental investigation of a 1/5 scale rail vehicle simulator
Rail vehicle dynamicists Frequently employ roller rigs to study the complex dynamic response of vehicles and trucks. This work presents the analytical and experimental investigation of a one-fifth scale model of a typical North American three-piece Freight truck running on a roller rig. The roller …

Accurate Wheel-rail Dynamic Measurement using a Scaled Roller Rig
… accurate dynamic measurements on a scaled roller rig designed and constructed by Virginia Tech and the Federal Railroad Administration (VT-FRA Roller Rig). The study also aims at determining the effect of naturally generated third-body layer deposits (because of the wear of the wheel and/or …
