30CrMnSiNi2A管材补焊件疲劳失效行为模拟
Simulation of Fatigue Failure Behavior of 30CrMnSiNi2A Pipe Weldment
摘要
Abstract
In order to explore the influence of repair welding times on the fatigue life of welded joint of 30CrMnSiNi2A pipe,finite element simulation software ANSYS Workbench and fatigue analysis software ANSYS nCodeDesignLife were used to establish the repair welding specimen model based on the actual shape and size of the welded part,and the fatigue life of the specimen was simulated.The results show that the mechanical properties and fatigue life of the heat affected zone decrease with the increase of welding times.The stress and strain concentration mainly occurs in the heat affected zone of the repair welding,so the fatigue failure starting position of the weldment under other repair welding times is here except for the first repair welding.关键词
