多支点过轨起重机金属结构有限元分析

摘要

介绍了多支点过轨起重机的基本参数,采用有限元技术,结合SolidWorks软件的壳单元,建立三维模型,在保证起重机各项性能的基础上,运用SolidWorks Simuliation对主要金属结构进行优化,合理地减轻了主梁的自重,保证了多支点过轨起重机整体使用性能.%The paper introduces basic parameters of multi-fulcrum over-rail crane. With finite element technology, the 3 D model is built considering the shell element in SolidWorks software. On the basis of ensuring crane performances, SolidWorks Simuliation is adopted for optimi2ation of main metal structures, which reasonably reduces self-weight of the girder and guarantees the overall operational performance of the crane.
