In this study, We have evaluated the applicability of the substructuring technique to reducing the computational cost of a three-dimensional analysis of a vehicle-track structure dynamic interaction. When the substructuring technique is applied properly to the three-dimensional dynamic interaction analysis, computational cost can be greatly cut down without loss in accuracy.
