Paper Title:
Welding Residual Stress's Numerical Simulation and Relieving of Guyed Mast Earplate Joint Substructure
  Abstract

The dynamic stress-strain and welding residual stress during welding are the significant factors which lead to welded cracking and debasement of the joint properties. Therefore, the welding residual stresses are still very importang problems.A large number of guyed mast accidents study shows that the welded joints of earplate and shaft were easily to be destroyed. Therefore, the accurate assessment of the guyed maste earplate joint substructure’s welding residual stress is of great significance. The theory and method of simulation of the welding temperature field and welding stress field by finite element method is first introduced, and then the earplate substructure refine model is established which was up to the welding numerical simulation. Based on ANSYS software’s APDL language to apply the welding heat source load, we can get and save the welding temperature field results at each time. Conversing the thermal analysis element into structure element to finish the caculation of the welding stress field. Eventually by adopting the elimination remnant technology to remove the part of welding residual stresses, we can got the final welding residual stress in different relieving proportion.
