Análise de vibração para detecção de defeitos em um motor de um refinador de madeira

Abstract

Vibration is a very common phenomenon on a day-to-day basis, whether in the industrial or even domestic environment. However, the vibration is often an undesirable problem that we face, due to the various malfunctions or wear it can cause to a particular device, and the pain and discomfort caused to humans working with devices subject to vibration. Often the vibration is inherent in the machine, so it will be necessary to reduce this vibration by inserting a material that absorbs such vibration or by vibration absorption techniques, such as component balancing. Knowing all these damages caused by the vibration outside acceptable levels, in this work, it will be first to collect the spectrum of a motor of a wood refiner, through a collecting equipment, for the analysis, we will make an analysis, based on the knowledge Theoretical, of these data collected, and then will be made a second analysis that will be compared with the previous reading to investigate defects and proposed methods to reduce this vibration. After this, a posterior analysis will be made to the application of the proposed method, in order to be able to prove the efficiency of the technique used to reduce vibration and also the method of reading of spectrum.
