| Abstract: | Considering its monolithic characteristic from integral casting, the design of type 203 cast manganese steel frog is introduced in this paper and its structure is simulated through finite dement methods. The separate static strength analysis under 21 load positions in 4 kinds of loading cases provides a theoretic foundation for rational design and intensification of the frog structure. The authors argue that the designed cast frog will guarantee its strength and be used reliably in the areas between nose rail and wing rail, which can be strengthened through adding transverse rib reinforcements. |
