摘要
本文提出了用有限元法进行架空线机械计算的数学模型和计算程序。有限元法是一种离散化的方法,它可以直接用来计算荷载不同、刚度不同的各种情况。它是在悬链方程基础上建立起来的,精度较高。本文对弧立档、连续档、特殊档的计算,提出了计算方法和步骤,并附有若干算例。
Using finite element method,this article presents a mathematical model and computer program for the mechanical calculation of overhead transmission lines. The finite element method is a dispersed method,so it can be used directly to calculate the status for different loads,rigidity,etc.Also it is with high accuracy for it is derived from the basic equation of catenary.This article gives the proce- dure and the method for the calculation of independent,continuous and speciad spans with some examples as well.
