Investigation of the some problems of running safety of rolling stock on the Ukrainian railways

Abstract

The results of the evaluation of the running safety conditions of railway vehicles are presented by means of computer simulation. Analysis of the possible reasons for derailment by means of performance evaluation of rolling stock and track interaction are presented. The impact of the technical condition of the dampers on the running safety of passenger wagons is considered. The localization of possible damages of bearing structures of high-speed train is determined with the help of calculation of the strength characteristics and the method of non-destructive metallography. There is the information about the development of software and hardware complexes providing an instrumental assessment of the technical condition of railway vehicles. Portable device is proposed for measuring the static load of the wheels of the rolling stock units on the track. The work on creation of stationary devices for automatic wheels fault detection in order to reduce the time period from the appearance of the defect was conducted. The brainchild of the mobile system of controlling running tests and dynamic diagnostics of rolling stock was considered.
