摘要
以TLJ900型高速铁路架桥机为例,重点研究分析了架桥机主金属结构部分的载荷工况和计算方法,针对架桥机的主梁、前后支腿等主结构在最不利载荷工况下的计算模型,以及整机的倾覆稳定性进行了分析研究。以期为类似高速铁路架桥机设备在结构设计计算方面提供一些有价值的参考。
Taking TLJ900 Bridge Girder Erection Machine for example,this paper mainly researches the load mode of the major metal structure,especially the structure of the main girder,and front and back jack under most disadvantageous work condition,and analyses the capsizing-proof stability of the erection machine,which may hopefully provide reference for the structural design of bridge girder erection machine for similar high speed railway construction projects.
