Keywords: high speed train, finite element method, mesh sensitivity.

Summary

Mesh sensitivity analysis is very important for the finite element analysis in areas with stress concentrations or with welds. The treatment of the meshes in the finite element analysis of the high speed train can significantly affect the computational results and then affect the design of the structures of the high speed train. The results obtained in current work can be summarized as follows:

From the comparison of different load cases with different meshes, the predictions of the stresses and displacements of the high speed train body are investigated in detail.
With the increase of the mesh density, the predicted displacement is increases to be closer to the actual value. But the predicted stresses can be higher than the actual stresses.
The mesh densities in the transition region hardly affect the computational results in the hot points of high stresses in the finite element model.
