| Abstract: | In order to research the fatigue capability of the railroad wagon coupler yoke,the fatigue comparative tests of No.13(foundry),No.13B(foundry),No.16(foundry),No.17(before-mend,foundry),No.17(foundry),No.13B(forging),No.16(forging) and No.17(forging) were carried out.The research results show that the whole fatigue performance of the forging coupler yoke is superior to the foundry coupler yoke. |
