A Study on the Shape Design of Wheel-Rail for Rolling Stock Seong, Gi-Deuk; Yang, Won-Ho; Jo, Myeong-Rae; Heo, Seong-Pil;
One of the main causes of severe wear or crack initiation in wheel and rail is the contact stress due to wheel-rail contact. In this paper, the shape design based on more reasonable contact stress analysis rather than a general Hertzian contact theory is investigated in order to reduce the contact stress. The optimal design is performed using the simple 2-D finite element model and its results are verified by 3-D finite element analysis.
