CONDITION MONITORING SYSTEM OF RAILWAY VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a condition monitoring system of railway vehicle catching abnormal vibration and detecting the trouble of traveling device components with a small number of sensors such as one for one truck. SOLUTION: The condition monitoring system of the railway vehicle is equipped with: a vehicle body floor vibration accelerometer 11 disposed on a vehicle body floor on the center of a truck of the railway vehicle; an axle box vibration accelerometer 12 for reference disposed in an axle box of a first axle 5 of a wheel; and a device calculating the ratio of vehicle body floor vibration acceleration to axle box vibration acceleration for reference in the strength of each frequency, and thereby the trouble of the traveling device components of the rolling stock is detected.
