To enhance the static and fatigue strength of undermatching butt joint of high strength steel under transverse loading,the influences of geometric parameters such as excess of weld metal,radius of curvature at weld toe,plate thickness and total width of cover pass in butt-welded joint on stress concentration factors at weld toe and weld root were studied by finite element method.
针对高强钢低匹配的横向对接接头形状设计,以最大限度提高接头静载承载能力和疲劳强度为目标,采用有限元计算的方法,考察了焊缝余高、焊趾过渡圆弧半径、盖面焊道宽度、板厚等几何参数对焊趾和焊根处应力集中的影响,回归分析得出的焊趾和焊根处的应力集中系数的经验方程式,对高强钢低匹配对接接头设计具有指导意义。
