    By using three different loading types, fifteen thin-wall box model beams of the crane were tested under a constant-amplitude fatigue loading. In consideration of the stress distribution on the section of the thin-wall box beam and the technological process of the welded construction, this paper analyzes the fatigue strength of the steel beam with welded stiffeners. The theory of fracture mechanics was used to analyze the crack growth rate and the fatigue life of the welded construction. The...

    By using three different loading types, fifteen thin-wall box model beams of the crane were tested under a constant-amplitude fatigue loading. In consideration of the stress distribution on the section of the thin-wall box beam and the technological process of the welded construction, this paper analyzes the fatigue strength of the steel beam with welded stiffeners. The theory of fracture mechanics was used to analyze the crack growth rate and the fatigue life of the welded construction. The analysis shows that the stress range and the size of the initial micro-flaw are significant factors in designing a given detail against fatigue.

    本文采用三种不同的加载类型,对15根起重机薄壁箱形模型梁在等幅疲劳载荷下进行了试验。考虑到在薄壁箱形梁中截面应力分布以及焊接结构的工艺过程,文中对带有焊接筋板的钢梁疲劳强度作了分析,并应用断裂力学的理论来分析裂纹扩展的速率和焊接结构的疲劳寿命。分析表明:在对一个给定的构造细节作抗疲劳计算时,应力振幅和初始微裂纹的尺寸是重要的因素。试验结果表明:在疲劳寿命中,应力振幅是决定性的应力变量。此外,对一个给定的构造细节而言,这个结果在双对数座标上应力振幅和循环寿命之间呈线性关系。本文在最后对焊接箱形梁的疲劳裂纹类型、扩展以及断口的问题作了论述。根据由疲劳试验数据得出的平均归线方程,提出了薄壁箱形梁的疲劳强度方程。
