Abstract
The implementation of Industry 4.0 in Brazil could result in annual savings of R$ 35 billion in repairs, R$ 31 billion with productive efficiency and R$ 7 billion with energy savings, totaling a saving of R$ 73 billion per year. Due to the impact that this innovation can bring, the Ministry of Industry, Trade and Services (MDIC), together with Brazilian Agency for Industrial Development (ABDI), launched the Brazilian Agenda for Industry 4.0 to prepare the country to embrace this trend and not lose the potential economic benefits that it brings. Structure maintenance can benefit from the innovations brought by Industry 4.0 by replacing costly preventive maintenance, in which specialists are called based on a prior schedule, with predictive maintenance, in which a monitoring system verifies the condition of the structure in an automated way and experts they are only triggered when there are indications of damage or potential failure. There is a rich literature containing studies that have researched various challenges in structural integrity monitoring. However, most studies in structural integrity monitoring focus on bridges and aerospace structures, while transmission line monitoring studies focus on galloping and ice formation on cables, without considering the structural side of the towers. A search conducted on 08/06/2022 in the Web of Knowledge using the keywords transmission tower and structural health monitoring returned just thirty-three references. Among the published works, the main techniques are based on analysis of modal parameters of structural vibration and machine learning based on simulations. In view of how poorly developed the studies in structural integrity monitoring in transmission towers are, it is concluded that this project has a strong potential for innovative contribution. This project proposes the creation of mechanical design in Computer-aided Design (CAD) based on the methodology Design Failure Mode and Effect Analysis (DFMA) and structural analyses by Computer-aided Engineering (CAE) of a small-scale virtual power transmission tower aimed at developing customized structural health condition monitoring solutions. It is expected that the tools to be developed in this project will help in the management of the power grid of Brazil, contributing to the improvement of the key indicators of maintenance performance. In addition to the creation of the mechanical project on a reduced scale and structural analysis will enable the construction of a proof of concept of the power transmission tower for future partnerships between the University and companies in the electricity sector of Brazil.
