摘要
目的分析大型高空作业平台力学性能,确定在3种不同工况下结构危险位置,探讨平台结构构件选择的合理性,为进一步的优化设计提供依据.方法借助ANSYS建立了以梁单元为基本单元的平台有限元分析模型,并根据吊篮的相关标准建立了3种典型工况,进而进行了平台静态分析,计算高空作业平台在不同工况下的应力强度和具体变形,对其进行分析比较.结果 ANSYS静态分析法得出的最大应力强度为114.978 MPa和最大变形为10.88mm均在设计要求的范围内,同时指出在危险工况下底部横杆、底部架与边立杆的连接位置是容易发生破坏的.结论高空作业平台满足力学性能要求,对3种不同工况下的危险部位进行了探讨,为悬吊平台的安全性提供依据,并能够为结构构件的进一步优化选择提供有效方案,具有重要实际意义.
This paper analyzes mechanical properties for 14 meters of large-scale aerial work platform, localization of dangerous section position under three different operating conditions, explores the rationality of the platform structure component selection provides the basis for further optimize design. Based on the finite element analysis software ANSYS, establishes in beam element as the basic unit of the platform finite element analysis model, and according to the related standard of suspended platform established three typical working conditions, then analyze the platform model in static, compute aerial work platform under different conditions of the stress intensity and deformation. ANSYS static analysis of maximum deformation 10. 88 mm and maximum stress intensity 114. 978 MPa in the design requirements, also pointed out danger part at the connection of bottom rail, bottom and edge pole in the structure. Aerial work platform meets mechanics performance requirements. This paper discusses the dangerous site of three different operating conditions,provides the basis for the safety of suspension platform and also provides effective solutions for further optimize the structure component selection, that has the important practical significance.
