2021 Principles Course Session
Vehicle-Track Measurement Technologies
An overview of vehicle-track measurement technologies (including both long-standing systems and state-of-the art developments) is provided. This includes coverage of the fundamental measurement principles and methodologies involved, as well as their practical application in railway system applications. Measurement system types discussed include: rail and wheel profile, track geometry, gage restraint and track modulus, lateral/vertical force, angle of attack and track performance, wheel impact load detection, rail stress / neutral temperature, and vision-based systems.
