This article describes the WRIM (wheel-rail interface management) model being developed by Transportation Technology Center to evaluate wheel-rail interface conditions, plan wheel-rail maintenance, and develop strategies to improve railway system performance. The WRIM software integrates wheel-rail profile measurement data, vehicle performance data, track geometry data, and rail steel properties to predict rail wear and RCF (rolling contact fatigue) based on the shakedown theory, an energy-based RCF damage function, and existing wear rate computation algorithms.
