  • A design method of rigid frog structure based on contact parameters was proposed in order to improve its wheel/rail interaction relationship. Using the method, the top profiles of nose rail and wing rail of No.12 rigid frog were optimized. The results show that the wheel/rail relationship can be improved effectively by lowering the height of the nose-rail section with the head width of 20 mm by 4 mm, eliminating the 1∶20 cross slope of the wing-rail head, and modifying the wing-rail head rising scope to be from the throat to the nose-rail section with the head width of 50 mm. Therefore, the proposed method is feasible and valid.
