摘要
通过对特重级起重量450t/80t吊车钢结构梁端突变截面应力及疲劳破坏等的分析比较,采用有限元分析计算,在实际设计中对传统钢吊车梁梁端突变截面进行了改进。
A technical modification is carried out on the abrupt transition section of traditional steel crane in the actual design through analyzing and comparing the stress and fatigue rupture of the abrupt transition section of the steel structure beam end of super-heavy 450 t/80 t crane and adopting finite element analysis and calculation.
