【摘要】：以某500 k V全联合变电构架为工程背景进行出线构架柱的受力分析,利用ANSYS有限元分析软件,获得3种连接刚度的单钢管柱及其相应独立杆的受力情况,得出内力与位移的空间作用影响系数,并与传统A型出线柱分析结果进行比较,探讨连接刚度和构架形式对计算结果的影响。研究表明:单杆柱构架较A型柱构架受力性能有一定的优越性。单杆柱出线构架空间作用影响系数存在一定的规律性和不确定性,不同工况下的不同内力需分别确定其系数。利用空间作用影响系数,可将出线柱模型简化为单杆模型进行研究分析。
[Abstract]:Taking a 500kV combined substation frame as the engineering background, the stress analysis of the outgoing frame column is carried out. By using the ANSYS finite element analysis software, three kinds of single steel pipe columns with connecting stiffness and their corresponding independent rods are obtained. The spatial effect coefficient of internal force and displacement is obtained, and compared with the analysis results of traditional A-type outgoing column, the influence of connection stiffness and frame form on the calculation results is discussed. The results show that the single bar column frame has some advantages over the A type column frame. There is some regularity and uncertainty in the influence coefficient of the spatial action of the single-bar column outer-line frame. The different internal forces under different working conditions need to determine the coefficients respectively. By using the influence coefficient of spatial action, the model of output column can be simplified into a single rod model for research and analysis.
