Abstract
In order to meet the global requirements of growing demand for fast production and the increase of quality, the industries need to keep their assets operational for as long as possible, then needing a maintenance plan suitable for their objectives. In industrial processes, a large part of the assets and machinery is composed of rotating machines, which, among various possibilities of defects and malfunctions, must always be properly balanced so that they can operate properly. This article presents the destructive power of unbalancing in rotating machines through a case study of a large exhaust system, where unbalance was diagnosed and fixed by using vibratory behavior monitoring. The theoretical concepts about the unbalance in this case study are presented in an analytical way and applied through a simulation using Kane's method, and also using experiments in a laboratory test bench. The results show that through the vibration analysis it is possible to monitor unbalance in rotating machines, increasing the reliability of the industrial plant and preventing failures, which causes economic losses and can also cause damage to the human health of workers exposed to an unbalanced machine. The simulations and laboratory experiments are good tools for a better understanding of the unbalance effects on the machine.
