Desenvolvimento de bancada didática de análise de vibrações

Abstract

Vibrations on rotating machines occur in a variety of ways and with varying frequency, depending on the cause factor they are subjected to, which leads to fatigue and subsequent breakdown of their components. Unbalance, as well as misalignment, are determining factors for these failures to occur. In this way, it is necessary to periodically and systematically monitor the machines, thus avoiding unexpected stops. Practical knowledge, combined with theoretical knowledge, provides a broader view of causation and possible solutions. This work aimed to develop a didactic workbench for vibration analysis, where several simulated situations of imbalance and misalignment can be created, allowing a perception closer to the reality of predictive maintenance in industrial rotary machines. For this, the conceptual design, the selection of necessary materials and the manufacturing of the mechanical parts were carried out. As a result, we obtained the prototype of the didactic bench for vibration analysis, which is available for use in the Laboratory of Vibrations, as well as the complete project so that this prototype can also be implemented by other educational institutions.
