O estado da arte da manutenção preditiva: opinião de especialistas

Abstract

The present work is a review of the state of the art of predictive maintenance exploring its history until we reach the prediction methodology, thus presenting its main concepts and techniques. This document contains information on prediction analysis through the study of vibrations, thermography and tribology, containing the main sources of defects that lead to each of these types of investigation, the study methods used, main measurement techniques, the most used instruments and advantages and disadvantages of each method. Subsequently, the best techniques for planning and analyzing the information obtained in the previously presented methodologies are presented, demonstrating that performing an analysis and effective planning is as important as applying a predictive method. Also shown is the best concepts and methods of management and control, pointing out their main indicators and philosophies employed for this purpose. Much of the process of continuous improvement goes through here, since it is at that moment that much of the planning is lost, is the control that makes the whole process is cyclical and ensures the evolution of the same over time. Subsequently is presented in this paper the horizon of predictive maintenance, with a search for what is most modern and what is expected to be the future of it, looking at the concept of industry 4.0. Finally, information on predictive maintenance theories, impacts of these applications and trends were subjected to an analysis of relevance, through a survey of maintenance managers from important companies in southeastern Brazil, using the Likert scale for this purpose. In which satisfactory results were obtained that corroborate with the author on the importance of the theme presented here.
