基于 ANSYS 的门座起重机金属结构建模

摘要

以 MQ1625型门座起重机为研究对象，介绍了其结构及主要尺寸。运用有限元分析软件 ANSYS 对起重机的门架、转台以及人字架结构进行了分步建模，并进行了金属结构整体有限元模型的创建。根据起重机的6种不同实际工况，对有限元模型进行了载荷和约束的添加，求解分析不同工况下门座起重机金属结构的静应力表现。分析了 ANSYS 建模及约束和载荷添加过程中出现的一些问题，并提出了相应的解决方案。%This paper takes the portal crane as the research object and firstly introduces the basic knowl-edge about its development and structure.Then by using finite element software ANSYS the static stress a-nalysis of the portal crane is conducted after the modeling of crane's metal structures,during which the constraints and the loads are added onto the model according to different working conditions of the crane. Finally several problems that arise during the modeling of the crane is analyzed with corresponding solu-tions put forward.
