Structural testing and finite element analysis of Y25 type bogie frame

Abstract

In this study, the structural behavior of the Y25 type bogie frame, commonly used in freight wagons, was comprehensively investigated using experimental tests and the finite element method (FEM). The test loads applied to the bogie frame were determined according to the EN 13749 standard, which is valid in the railway industry. In the experimental studies, uniaxial and triaxial (rosette) strain gauges were placed on critical areas of the frame, allowing direct measurement of stress distributions under loading. To validate the experimental results, a detailed finite element model was created in ANSYS Workbench software, and stress-strain calculations were performed under the same loading conditions. Shell elements (SHELL181), which represent frame rigidity, were specifically preferred in the analyses, and boundary conditions were defined to be consistent with the experimental setup. A high degree of agreement was observed when comparing the stress values obtained from experimental measurements with the numerical results. These results demonstrate the accuracy and reliability of the developed finite element model. The study presents important findings regarding the safety and strength performance of the Y25 type bogie frame by combining both experimental and numerical approaches.
