摘要
以高速铁路架桥用的9000kN运梁车为研究对象,运用大型有限元软件对其结构进行强度与屈曲稳定性计算,分析了该运梁车的应力分布,指出其屈曲稳定性的危险部位,为该运梁车结构改进和现场施工监控提供参考。
Aimed at 9 000 kN girder transporter for high-speed railway bridge construction, the structural in- tensity and flexure stability are calculated with the finite element software. The stress distribution of girder trans- porter is analyzed, and the dangerous parts of flexure stability are found out, which provides reference for structure improvement of girder transporter and monitoring construction.
