Research on Hexahedral and Tetrahedral Mesh Applied to Strength Analysis of Bogie Frame

Abstract:

The structure of bogie frame is meshed by hexahedral and tetrahedral elements respectively. FE analysis is taken based on the loads defined by JIS E 4207 standard and the stress distributions of two separate models are obtained. To clarify the accuracy of two kinds of finite element models, the bench test of the bogie frame is carried out. It shows that both the hexahedral and tetrahedral models are valid according to the comparison between FE results and experimental values when the structural model is regular. However, for complex structure model 10-node tetrahedral model takes precedence.
