    1设计项目摘要本次设计在参照同类塔式起重机基础上,对 QTZ40 型塔式起重机进行总体设计及吊臂的设计。在吊臂设计工程中,采用了有限元法对其进行分析计算,采用了 ANSYS10.0 软件进行分析。按照整机主要性能参数,确定各机构类型及钢结构型式,主要确定了吊臂的结构参数,并按照吊臂端部加载、跨中加载及根部加载三种工况分析。通过对吊臂作适当的简化,应用 ANSYS10.0 软件建立吊臂有限元模型,施加各工况载荷,进行求解,进而可得各工况下各节点受力情况及各单元所受轴向力、轴向应力大小及各工况下吊臂的变形挠度大小,并能演示吊臂加载过程的动画,清晰的展现了各工况下吊臂的受力性能。通过修改模型参数,对不同模型进行分析比较。由比较不同模型在相同工况下的受力状况及刚度状况,综合分析强度和刚度条件,可得出受力最为合理的一组模型参数,通过对此组参数下模型进行强度及刚度校核,进而获得吊臂的最终参数结果。关键词:QTZ40 型塔式起重机 吊臂 有限元分析 ANSYS10.0AbstractRefers to the similar tower crane, this design is composed by the system design and the lazy arm design to the QTZ40 tower crane. In the lazy arm design progress, it has carried Finite Element method on the analysis computation, and used ANSYS10.0 software.According to the entire machine main performance parameter, various organizations type and the steel structure pattern has been determined. The design parameter of operating modes which are composed of nose increase, the cross center increase and the root increase. Through the suitable simplification to the lazy arm, the lazy arm finite element model is establishment applied ANSYS10.0 software, and then exerted various operating modes load, carried on the solution. Then ANSYS10.0 software can calculate various pitch points stress situation, various units receive the axial stress size, and the lazy arm distortion size under various operating modes. Also it can demonstrate the animation in the process of the lazy arm increase. It has clearly displayed the lazy arm stress performance under various operating modes.Through the revision for model parameter, the analysis comparison is carried on the different model. Because the stress condition and rigidity condition of different model is compared under the same operating mode, and the generalized analysis intensity and the rigidity condition is carried on, a most reasonable model parameter can be obtained, though the intensity and the rigidity examination regarding this model, then the final parameter result of the lazy arm can be obtained.Key words: QTZ40 tower crane Lazy arm Finite element analysis ANSYS10.0目 录第 1章 前言··········································································11.1 概述················································································11.2 发展趋势·········································································1第 2章 总体设计····································································22.1 概述···········································································22.2 确定总体设计方案····························································22.3 总体设计原则·································································292.4 平衡臂与平衡重的计算······················································302.5 起重特性曲线·································································322.6 塔机风力计算·······························································332.7 整机的抗倾覆稳定性计算·················································432.8 固定基础稳定性计算·······················································49第 3章 吊臂的设计计算························································503.1 分析单吊点与双吊点的优缺点·············································503.2 吊臂吊点位置选择··························································513.3 吊臂结构参数参数··························································523.4 有限元模型建立过程的几点简化··········································533.5 吊臂结构的有限元分析计算················································543.6 计算结果分析································································693.7 吊臂强度校核································································763.8 吊臂稳定性校核·····························································76毕业设计小结······································································87致谢··················································································88参考文献············································································89计算与说明结果2设计项目摘要本次设计在参照同类塔式起重机基础上,对 QTZ40 型塔式起重机进行总体设计及吊臂的设计。在吊臂设计工程中,采用了有限元法对其进行分析计算,采用了 ANSYS10.0 软件进行分析。按照整机主要性能参数,确定各机构类型及钢结构型式,主要确定了吊臂的结构参数,并按照吊臂端部加载、跨中加载及根部加载三种工况分析。通过对吊臂作适当的简化,应用 ANSYS10.0 软件建立吊臂有限元模型,施加各工况载荷,进行求解,进而可得各工况下各节点受力情况及各单元所受轴向力、轴向应力大小及各工况下吊臂的变形挠度大小,并能演示吊臂加载过程的动画,清晰的展现了各工况下吊臂的受力性能。通过修改模型参数,对不同模型进行分析比较。由比较不同模型在相同工况下的受力状况及刚度状况,综合分析强度和刚度条件,可得出受力最为合理的一组模型参数,通过对此组参数下模型进行强度及刚度校核,进而获得吊臂的最终参数结果。关键词:QTZ40 型塔式起重机 吊臂 有限元分析 ANSYS10.0AbstractRefers to the similar tower crane, this design is composed by the system design and the lazy arm design to the QTZ40 tower crane.
