This study investigates the influence of wheelset bracket orientation on the load transfer mechanism and structural performance of railway bogie frames using finite element analysis. Three configurations, namely vertical, horizontal, and cross orientations, were modeled and evaluated in ANSYS Workbench under identical material properties, boundary conditions, and loading scenarios. Static, dynamic, and impact loading conditions were considered to assess stress, deformation, and structural safety. The results show that bracket orientation significantly affects load distribution and structural response. Among the investigated configurations, the horizontal orientation exhibits the most favorable performance, characterized by lower stress concentration, reduced deformation, higher stiffness, and improved safety margins. In contrast, the vertical orientation demonstrates the most critical response and operates closer to the material yield limit. These findings confirm that wheelset bracket orientation is an important design parameter influencing the reliability, durability, and structural efficiency of railway bogie frames.
