摘要

This paper attempts to analyze dynamic wheel / rail rolling contact through application of a three-dimensional finite element method with large-scale parallel computing. This analysis clarifies the dynamic behavior of the contact patch, when a wheel rolls on a rail at a high speed with loading torque. A rail model which allows efficient calculation was developed to accelerate a wheel on a small size rail model. In addition, this method employs dynamic mesh partitioning to maintain meshes in the contact patch in one partition region during the wheel rolling for efficient parallel calculation. Using this method has made it possible to evaluate the dynamic wheel / rail rolling contact behavior.
