摘要
利用大型有限元软件ABAQUS对某公司YZS14060吨铸造起重机主梁结构进行模态分析,分析了主梁在起重机工作过程中产生的振动情况。提取其前10阶模态固有频率与对应的振型,并对其进行分析,得到了较为准确、直观的结果,为此类产品日后改造生产提供重要参考。
The modal analysis of the 140 tons of casting crane girder structure is carried by the large finite element software ABAQUS. The vibration of the girder in crane＇s working process is analyzed. And the first ten natural frequencies and corre- sponding vibration modes are extracted and are also analyzed, then the more accurate and intuitive results are got, which pro- vides a important reference for the further transformation of such products.
