The Impact to the Guyed Mast Welding Earplant Joint's Wind-Induced Cumulative Fatigue Damage by Different Eliminate Proportion of Welding Residual Stress

Abstract:

This paper proposes a method to quantitative assess the impact of welding residual stress to structures cumulative fatigue damage. We use ANSYS finite element software to eliminate the welding temperature field and welding stress field, and by changing the load order, preheat consider we can get the welding residual stress of different eliminate proportion. Based on critical damage plane method we finish the welding earplant joint s wind-induced cumulative fatigue damage by different eliminate proportion of welding residual stress .
