摘要
针对大跨度输电线铁塔组立所用的特种起重机械——抱杆结构,采用有限元软件建立了两种抱杆空间三维模型,分三种工况对抱杆结构进行了强度、特征值屈曲分析和非线性特征值屈曲分析;研究表明,抱杆在三种状况下的强度、稳定性及变形均满足设计要求。
The holding pole is a special crane made for assembling and hoisting.Two 3-dimensional models were constructed by finite element analysis software.This paper analyzed the strength,the eigenvalue buckling and the nonlinear eigenvalue buckling under three conditions.The research results showed that the proposed holding pole model can meet the requirement of design in strength,stability and variability.
