Research on influence of welding root node coupling on welding deformation of large mining dump truck frame
Xuzhou XCMG Mining Machinery Co. Ltd, Xuzhou, J S 221004, China
Taking the frame of large-scale mining dump truck as the research object, it established the model of coupling or not of T-joint welding root by the finite element analysis, and analyzed the deformation of coupling or not of T-joint welding root. The deformation trend of the two cases is the same, which verifies the correctness of the prediction results of deformation. The results show that the maximum deformation occurs at the arc starting welding of the vertical plate, and the error between the simulation results and the test results is small. At the same time, the deformation error of gantry frame and hinge-hole at the key position can meet the production requirements, which is of great significance to the field production.
