Application of different structures railway wheel in instrumental wheelset

Abstract

The identification of the dynamic behavior of railway vehicles is a combination of theoretical and experimental approach. Main aspects are analyzed the problem of continual measurement of contact forces "wheel-rail" with the help of a instrumental wheelset. Among the most important experimental tests of railway vehicles is the study of traffic safety and study the behavior of railway vehicles passing through S curves. The main problems in the development of the instrument wheels are analyzed, which are related to the determination of the optimal position, the number and way of connecting the strain gauges, as well as the calibration of the instrumental wheelset. Presented are stand for calibration and measurement procedure of the contact forces "wheel-rail", realized in the laboratory of the Center for railway vehicles Faculty "Mechanical and civil engineers" - Kraljevo, University of Kragujevac, Serbia. Special attention is paid to the application of FEM to determine the optimal placement of strain gauges for wheels construct used by railway companies in Bulgaria. The presented simulation with the application of the Solid Works system is a preliminary tool for starting the research process.
