Development of the transmission tower virtual 3D model for structural analysis in ANSYS

Abstract

This paper describes a methodology for transmission tower 3D modelling. The task was to develop a virtual 3D model, corresponding to the real structure, which will be subjected to structural analysis in ANSYS software. The process of 3D modelling is crucial for this kind of computer analysis. It requires precise key point coordinates defining. Not only the important points of the structure, but also the points of interest for the future structural analysis have to be defined. This means that model developer should be familiar with the structural analysis so he could form adequate key points in advance. The main point of the experiment concept is to determine dynamic behaviour of the structure, exposed to a known load. Truly correlated 3D model, with verified geometric, static and dynamic properties offers the opportunity to predict the structure behaviour under loads that can hardly apply on a living structure (extreme overloads, complex loads, and harsh ambient condition).
