Running Safety

In this study, using the analysis program DIASTARS III that is able to take into account the dynamic interaction between railway vehicles and railway structures, we conducted seismic train-running analysis on a model line that is about 4.8 km long. And we identified the relative weak structures of seismic train-running safety in the model line.

Freight Wagons

Operation of the rolling stock is associated with a number of risks. The consequences of failures are sometimes very serious - safety or the environment, sometimes only economic. A significant factor affecting the safe operation of railway vehicles is maintenance. The paper presents methods of risks assessment and possibilities of their reduction in design, operation and maintenance of railway vehicles. Special attention is given to the new "silent brakes" and safety related issues for freight wagons.

The lexical meaning of derailment shall be the wheels of trains going off the track and it is an important factor for the running safety of railway vehicles. For the measurement of interaction forces between the wheel and the rail, wheel set is used with normal method and the vibration accelerometer is used with simplified method to assess the safety of a railway vehicle in the derailment process. The result has been recorded by measuring vibration acceleration.

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.
