The bogies used in railway vehicles are composed of frame, suspension system, axle and wheel. The shape of bogies as well as the load conditions they face during operation, such as static load and dynamic load, are very complex. Therefore, various tests including static load tests, fatigue tests, and track tests are required to design and eva‎luate bogie strength. The bogie frame as the main structure bears the loads of the wagon body. Although the standards prescribe methods for eva‎luating the strength of bogie frames, they do not define detailed approaches for eva‎luating fatigue life. During the life of a bogie frame, the frame experiences different loading conditions, the most difficult of which is the part where the train passes through the arch. The theories of stability and arc crossing have been formulated and adapted to modern computational methods, which form the basis of the elements used in the standard simulation software used regularly for the design and analysis of railway vehicles. New formulations allow faster assembly of various suspension systems and easy inclusion of non-linear elements in the bogie. Vertical, longitudinal, transverse and torsional loads are applied to the moving bogie frame. Verifying the safety of the bogie frame requires resistance testing under maximum load conditions. In this research, while introducing the structure of the bogie and the elements used in it, it has been tried to provide a complete description of the types of forces and stresses in the bogie bowl and the train axle in Y25 and 18-100 bogies while moving in curves.
