Improved railway wheelset–track interaction model in the high-frequency domain

作者:

Highlights:

• 3D Moving Element Method (MEM) to model the track is proposed.

• The model considers an Eulerian coordinate system attached to the moving vehicle.

• The resulting formulation permits to reduce the computational cost compared to the FE models commonly used.

• The proposed 3D MEM track model is suitable to describe the high frequency dynamics.
