Abstract
An amount of wear of a railroad vehicle wheel flange online while traveling in a curved section is directly measured. A laser rangefinderis installed on an outer track side in a rounded curve section of a railroad track. When a railroad vehicle travels through the rounded curve section, the laser rangefindermeasures a distance to a front rim surface of a wheel on an outer track side of a wheelset in a forward direction of travel of a bogie forming a vehicle. The amount of wheel flange wear is obtained by comparing this measured distance with a previous measurement of the measured distance. It is then possible to control the amount of wheel flange wear when traveling in a curved section, thus making it possible to quickly find wheels having flange wear that has exceeded a control range and ensure safety during travel of the railroad vehicle.
