Influence of Diagnostics of Axle Boxes of Freight Cars on Traffic Safety of the Railway Transport

Abstract

EN: Abstract. Failures of axle boxes of freight cars due to poor-quality repair and maintenance can be reduced by applying diagnostic methods and tools. Therefore, the study carried out a study of the influence of diagnostics of axle boxes of freight cars on traffic safety of the railway transport. To reduce the magnitude of risks arising from failures of axle box units of freight cars, it is proposed to use vibration diagnostics during maintenance and repair, and to exclude the human factor, it is proposed to completely eliminate the operator's influence on the conclusions of the diagnostic process. Also, a method for assessing the risks arising from failures of axle boxes of freight cars was developed. The presented method for assessing of traffic safety the railway transport allows you to determine and predict risks. Vibration diagnostics allows reducing the risks arising from failures of axle boxes of freight cars, thereby increasing the level of traffic safety up to 3.7 times. In this regard, it can be argued that the use of vibration diagnostics during the maintenance and repair of axle boxes of freight cars makes it possible to reduce the threats to human life and possible harmful environmental consequences on the railway transport.
