针对超大吨位全地面起重机,在分析其传统支腿刚度和强度基础上提出拉索式支腿结构。采用有限元分析和试验两种方法,研究拉索式支腿与无拉索支腿的承载特性。结果表明,拉索式支腿在刚度和强度上较无拉索支腿均有较大提升,可为大吨位起重机支腿结构布置和轻量化设计提供参考。
For the large tonnage all terrain crane, based on the analysis of the traditional leg stiffness and strength of the proposed cable-type leg structure. The finite element analysis and test methods are used to study the bearing characteristics of cable-stayed and cable-free outriggers. The results show that the strength and strength of the outriggers are much higher than that of the outriggers, which can provide reference for the structural design and lightweight design of the outriggers.
