MONITORING INSTRUMENTS MOUNTED ON SCHEDULED RUNNING COMMERCIAL TRAINS (INSTRUMENTED REVENUE VEHICLES, IRV) MAKE USE OF NEWTON`S LAWS OF MECHANICS FOR TRAIN BASED AND IN-SERVICE TRACK-CONDITION MONITORING IN TARGET PLANING OF MAINTENANCE

Published on: April 22, 2018December 12, 2023 by Chaminda Weerawarna

The Newton`s Laws Mechanic is useful to analyse mutual track-vehicle/wheel-rail interactions and to determine track irregularities and track defects by vehicle mounted instruments: Accelerometer Sensors and Gyroscope Devices for Rotation Measurements. This means, by measuring accelerations and rotations through instruments on board of commercial and scheduled running rail-vehicles, the cause in form of track irregularities […]
