Stress Analysis of Typical Welded Joints for Locomotive Body
In recent years, there was a big difference between the theoretical results and experimental results of typical welded jointsof the transition zone of draft beam and the center beam in the structural analysis of heavy-loaded locomotive body when using the shellelements. In order to solve this proble...

| description | In recent years, there was a big difference between the theoretical results and experimental results of typical welded jointsof the transition zone of draft beam and the center beam in the structural analysis of heavy-loaded locomotive body when using the shellelements. In order to solve this problem, it was presented that using the shell element and solid element to disperse typical welded joints ofthe transition zone of draft beam and the center beam. Based on the operation conditions of locomotive, the theoretical stress distributionof longitudinal compressive and tensile load cases were decided, which were also compared with the experimental results. Effect of shelland solid element for the stress distribution of typical welded joint was studied; the region’s local structure had also been optimized. Theresults show as follows: in the typical weld joint area, solid element have a more precise calculation than the shell element, and has a highdegree of agreement with the experimental results; using the solid element can accurately simulate the stress distribution of high stressconcentration welded joints. |
