The paper is part of the publication series, which describe the most significant and innovative research and development design solutions and computational procedures as part of European structural funds project. The object of this article is strength conditions assessment of changed structure of three axle bogie frame, which is characterized below by higher axle loads combined with good operational properties. The occasion of change was the unstable behaviour of the system during prototype tests. For validation of the new structure design, there has been created a substitute simulation model in program ANSYS. Results of calculations prove, that new structure of the bogie frame satisfies strength assessments.

This publication is the result of the project implementation: Development of two types of freight wagon with bogies for non-standard wheelbase or track wheelset, complying with the criteria for interoperability, environmental issues, safety and reliability ITMS: 26220220070 supported by the Operational Programme Research and development funded by the ERDF.
