摘要
Abstract
For the problem that the welded track of the yard crane is prone to fatigue cracking during running,the pa-per mainly studies and proposes a serial of technology improvement measures to perfect the anti-fatigue performance of the track welding joint.Compared to traditional technology,the study focuses on the effect of the leg size and welding position on anti-fatigue performance of the welding joint.Compared the test result with the simulated result,it’s found that increas-ing the size of the upper leg can significantly improve anti-fatigue performance,while changing the welding position has lit-tle effect.关键词
