Abstract

The focus of much research into the wheel/rail interface has been on the track side of the equation. But there are system benefits to be derived from understanding the mechanisms that affect wheel life and maintenance requirements as well. This article looks at the diverse factors that affect the wheel side of the equation. Wheels, like rail, do not operate in isolation. Their performance is affected by a number of vehicle-. track-, and operating-related factors. Among the more critical are: dynamic vehicle/track interaction, track irregularities, track stiffness, and increasing axle loads.
