特大型龙门吊主梁提升结构设计与优化
|
摘要
分析特大型龙门吊提升的工艺及影响因素;基于主梁的结构形式与特点,对主梁提升过程中受力集中区域进行结构设计;采用ANSYS Workbench软件建立有限元模型,添加约束与多工况载荷,进行强度计算,并对计算结果进行分析;并对设计方案进行优化,为主梁提升的结构设计提供依据。
In this paper,the hoisting process and influencing factors of oversize gantry crane are analyzed. Based on the structural form and characteristics of the main girder,structural design for the stress concentration area of the main girder in lifting process is carried out. The finite element model is established by using the ANSYS Workbench software; constraints and multiple working conditions are added to calculate the strength,and the calculation results are analyzed. The design scheme is then optimized so as to provide a basis for design of the girder lifting structure.
