Analysis of tendencies of freight wagon axle-box temperature mode formation

Abstract

The determinant factors of freight wagon axle-box temperature modes during rolling-stock exploitation are analysed. These factors are axle-box mileage, axle-box operating time, defects of the rolling surface of wheel and ambient temperature. The temperature of freight wagon axle box considering registered data the consist patterns and reasons of axle-box temperature alteration are defined during the monitoring. The dependence of freight wagon axle-box failures, fixed by rolling-stock automatic control equipment, on axle-box running mileage and lifetime are analysed. Finally, basic conclusions are given.
