Numerical study of freight wagon bogies to increase axial load from 20 tons to 22.5 tons using finite element method

This article compares the characteristics of the improved bogie used in the long-edge mineral freight car to bear the axial load of 22.5 tons with the original H665 bogie. The H665 bogie is being used in the Middle East and specifically in the cargo fleet of Iran. Static and vibration analysis of individual parts and the infrastructure of railway vehicles is an integral part of designing and improving the performance of railway vehicles. Therefore, static and vibration analysis of the bogie frame was performed in our model using the finite element method. The Abaqus software package performed numerical calculations based on the FEM approach. In this research, theoretical results related to structural stress values , natural frequencies, and shape of vibration modes of the improved bogie and the original bogie were extracted. While comparing the results, the amount of structural stress reduction and the feasibility of increasing this axial load were investigated.
