摘要

本文从输电线路中单个电缆段的实际问题出发，对接触网型结构进行了有限元建模。有限元模型允许使用电缆的几何和物理数据对给定结构的变形位置和应力状态进行分析。建立了考虑温度变化和附加荷载的梁型线性/非线性有限元模型。这类模型的另一个应用是在动压作用下空中加油索的求形。计算结果采用商用有限元软件ANSYS进行计算。

FEM Applications of Catenary Type Structures

The paper deals with Finite Element Modeling of catenary type structures starting from practical problems related to a single cable segment in the case of an electric transmission line. Finite element models allow the analysis of the resulting deformed position and stress state for a given configuration obtained by using the geometric and physical data of a cable. Beam type linear/nonlinear finite element models which can take into account also the temperature variation and extra loading on the cable were developed. Another application of this type of models is for the case of form finding of aerial refueling cable subjected to dynamic pressure. The results were obtained by the commercial finite element software ANSYS.
