Measuring systems for testing the safety and security of railway vehicles

Abstract

The paper presents the measuring systems for testing the safety and security of railway vehicles that are in recent few years developed and built in the Center for Railway Vehicles at the Faculty of Mechanical Engineering Kraljevo. The measuring systems are based on wireless signal transmission and allow testing of quasi-static and dynamic characteristics of railway vehicles in accordance with UIC 518 regulations– quiet running and running safety of railway vehicles and UIC 530-2 – Wagons – Running safety (Testing the railway vehicles behavior in repression through the S curve). The following topics are presented in this paper: the measuring system for measurement of lateral force Y and the vertical force Q that occur in contact between wheel and rail, as well as their ratio Y/Q; the test stand for calibration and testing of instrumented wheelsets; the measuring system for measurement of lateral force H and acceleration in the height of axle-box; the measuring system for measurement of the height of wheel lifting; the measuring system for measurement of acceleration of the wagon body; the measuring system for measurement of compressive force at the autocoupler; the measuring system for measurement of lateral movement between wagons; and the measuring system for measurement of temperature in the axle-box. For all measuring systems special software is developed, that allow easy control and adjustment, as well as visualization and storage of obtained measurement results.
