Interaction of the TE33a Diesel Locomotive and the Railway Track on Curved Section with Radius 290 m

Abstract

The purpose of the research was an experimental study of the dynamic processes of interaction between a TE33A diesel locomotive and a railway track when passing along a curved section with a radius of 290 m. To study the dynamic and driving properties of the rolling stock, the analysis of the experimental data obtained was carried out. When performing the study, the following results were obtained: the indicators of the frame forces of each wheel were determined when moving the TE33A locomotive along a curve with a radius of 290 m; the coefficients of the vertical dynamics of the second suspension stage when moving the TE33A locomotive along a curve with a radius of 290 m are determined; axial stresses in the rails under the influence of the TE33A locomotive on the track with rails of grades R50 and R65 are determined.
