摘要:

应用有限元分析软件,实现了对一人字形变电构架的高等分析,论述了高等分析的过程.通过对高等分析和传统一阶弹性分析的计算结果的分析对比,初步讨论了传统一阶弹性计算中的缺陷,以及对人字形电力构架进行高等分析中几个主要因素对结果的影响.计算结果表明:几何非线性对于人字形结构影响比较大;在用高等分析选取杆件单元时,应充分考虑较大轴力的杆件单元;二阶效应对内力的影响由下向上逐渐减少.

Abstract:

Using the finite element analysis software, the advanced analysis of a herringbone transformer architecture is realized, and the process of advanced analysis is discussed. Through the analysis and comparison of the calculation results of advanced analysis and traditional first-order elastic analysis, the defects in traditional first-order elasticity calculation and the influence of several main factors in the advanced analysis of herringbone power architecture are preliminarily discussed. The calculation results show that the geometric nonlinearity has a great influence on the herringbone structure. When selecting member elements with advanced analysis, fully consider member elements with large axial forces; The influence of the second-order effect on the internal force gradually decreases from the bottom up.
