Paper Title:
Study on the Residual Stress Test of Welded Joints for Wind-Driven Generator Base and Numerical Analysis
  Abstract

In order to know the concrete distribution of welding residual stresses in Megawatt wind turbine’s basis, Msc.Marc codes by finite element method were applied to simulate temperature and stress field of the base’s welded joints which were appeared on the screen by 3D real-time dynamic numerical, the distribution of welding temperature field and the residual stress is obtained and then the test results of welding residual stress are checked by Blind-hole method. The welding residual stress in the condition of anneal and non-anneal was comparatively analysed. The results show that the transverse and longitudinal residual stresses in the area near the weld are comparatively larger, and the variation trend of the transverse and longitudinal residual stresses in the area far away from the weld are nearly the same. It means that the FEM determination results coinciding with test results are available for reference to the design of the Wind-driven generator welding structure.
