The mechanical stress due to the wheel-rail contact and thermal stress due to the drag braking increase the incidence of wheel failure. So, firstly, stress analyses(mechanical, thermal and combined stress) of wheel plate are performed using 3-dimensional finite element method(FEM). Secondly, the optimum design of wheel plate is investigated in order to reduce weight of the wheel based on results of stress analysis. The optimum design is performed using 2-dimensional axisymmetric F.E. model and its results are verified by 3-dimensional F. E. analysis. [ABSTRACT FROM AUTHOR] |
