DETECTION OF DEFECTS IN THE RAILWAY TRACK THAT CAN INFLUENCE TRAFFIC SAFETY USING THE METHOD OF VIBRATION ANALYSIS OF VEHICLE-RAIL SYSTEM

Ioana Maria MIHĂILESCU, Gabriel POPA, Răzvan OPREA

Abstract


This paper presents a study of the vertical vibrations, on the Z axis, of a standard tank wagon, on 4 axles, Zacs type. It analyzes and compares the vibrations induced on the bogie boxes of the loaded and empty wagon at the points where the major deviations from the standard dimensions of the railway were measured. The measurements were recorded on a curved railway with a radius of curvature of 1800 m, on the ring from the Railway Testing Center from Făurei at a speed of 135km / h. The analyzed data is transposed in diagrams that reflect the influence of the railway profile in the movements of the wagon in motion in a curve.
