A Study on the Shape Design of Wheel-Rail for Rolling Stock

철도차량용 휠과 레일의 형상설계에 관한 연구

  • Published : 1999.11.01


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.
