ABSTRACT
The contribution presents a modification of a goods wagon bogie frame. Every newly designed or significantly modified any support part of a railway bogie must meet strict criteria related to its strength and fatigue life. It presents key changes of the structure of an original goods wagon bogie frame, conditions and results strength analyses for unfavourable load cases, for which values of load forces come out from valid standards. The introductory part presents the original goods wagon bogie and the idea of its modification. In the next part analyses of structural properties (modal and stress analyses) are introduced. Simulation computations were carried out using Finite Element Method. Further, main load cases which all bogies must meet before commissioning and conditions for bogies approval are described. In simulation calculations a goods bogie frame was loaded in compliance with standards by four unfavourable load cases.
