摘要
为研究铁路货车钩尾框的疲劳性能,对铁路货车13型、13B型、16型、17型(改进前)、17型铸造钩尾框及13B型、16型、17型锻造钩尾框进行了疲劳性能对比研究,初步研究结果表明锻造钩尾框的整体疲劳性能优于铸造钩尾框.
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.
