Geometrical Modeling of Icing Process on the Conductors of Overhead Power Transmission Lines
Journal Title: Металлические конструкции - Year 2016, Vol 22, Issue 1
Abstract
Questions, touching geometrical modeling of simulation of icing process on the conductors for overhead power transmission lines, are considered in the article. The goal – definition and predictive modeling of ice load on OPTL constructions. The task of this research is to obtain the analytical description and the construction of a theoretical model of the surface icing of the conductor OPTL. Under the theoretical model is meant approximate, analytical determination of the surface, corresponding to the initial materials for modeling. For achieving this goal, it was done mathematical modeling, which is based on experimental studies on physical modeling of ice on conductors in the laboratory. As a principled approach it is suggested to transfer from physical parameters to geometrical for solving tasks.
