Structural analysis of a modified freight wagon bogie frame

Abstract

This paper presents results of selected load cases for the modified freight wagon bogie frame. It comprises of two main parts. The first part is addressed to the introduction of a modified freight wagon bogie. There are described conditions for rail vehicles approval and mainly load cases which every bogie must meet for commissioning. The next part deals with computer modelling and analyses of a frame of this modified freight wagon bogie. It was analysed using the FE method and calculations were focused on the assessment of stresses of the frame structure under exceptional load. Calculation conditions were based on valid standards.
