输电线路覆冰严重时,可能导致线路断线、线间闪络、铁塔倒塌等事故,严重影响电网的稳定运行。为了更深入地了解输电铁塔关键构件的力学特性,提高其运行质量并降低运维成本,本文利用COMSOL和MATLAB设计了一个具有交互功能的输电铁塔力学仿真界面。用户可以根据需要输入不同的仿真参数,并通过点击不同电压等级下的输电铁塔类型节点进行关键构件的力学仿真和参数计算。该仿真界面实现了输电铁塔的几何建模、网格剖分、仿真结果云图展示以及关键构件的最大节点位移、最大轴向应力等力学参数的动态输出。同时,根据输出参数对输电铁塔的力学失效状态进行评估。界面操作简单直观,用户可以快速获取仿真结果,有助于加深对输电铁塔关键构件力学仿真的理解。这对于开展输电铁塔关键构件的运行维护工作,提高输电铁塔的运行质量具有重要意义。

Severe icing on transmission lines can lead to line breaks,flashovers between lines,and tower collapses,severely affecting the stable operation of the power grid.To gain a deeper understanding of the mechanical characteristics of key components of transmission towers and improve their operational quality while reducing maintenance costs,this paper presents an interactive mechanical simulation interface for transmission towers designed using COMSOL and MATLAB.Users can input different simulation parameters and perform mechanical simulations and parameter calculations of key components by clicking on the nodes of transmission tower types under different voltage levels.The interface facilitates geometric modeling of transmission towers,mesh partitioning,displaying simulation result contour plots,and dynamic output of mechanical parameters such as maximum nodal displacement and maximum axial stress of key components.It also evaluates the mechanical failure state of transmission towers based on output parameters.The interface is straightforward and intuitive,enabling users to quickly obtain simulation results,thus enhancing their understanding of the mechanical simulation of key components of transmission towers.This is significantly important for conducting maintenance operations of key components of transmission towers and improving their operational quality.
