摘要
塔身是塔式吊车的重要组成部分,利用大型有限元软件ANSYS对某塔式起重机塔身进行工作及非工作状态分析计算,得到了塔身工作及非工作状态总位移分布云图、各种状态下塔身当量应力分布云图;根据分析结果对其结构进行了优化,有效控制了可能出现的危险,增强了设备的安全性。
Tower-body is the import part of the tower crane. The application of large-scale finite element analysis software-ANSYS for an analysis and calculation of Tower-body of Tower Cranes in working and nonworking state are introduced. The distribution of the total displacement of cloud in working and non-working state ,various state Tower-body equivalent stress distribution of cloud are given. According to results of the analysis,its structure has been optimized,the risk is controled effechiveey and the safety of the equipment is enhanced.
