ANALYSIS OF VIBRATION EFFECT ON FACTORY FOUNDATION IN A FLOUR MILL

Abstract

Thirteen roller machines, in operation at a flour mill, all on one floor, were analyzed for spectra transmission and propagation, using a vibration analyzer. The vibration analyzer was placed at 8 different positions around each roller machine, generating unique spectra curves symbolic of signals transmitted. It was observered that with exponential characteristics above 2 in the polynomial equations  resulted in significant signal propagation requiring isolation of the machines necessary. Results indicates that out of the 7 machines requiring isolation, cork  would be needed for 3 with maximum displacement of 0.19 to 0.20mm, while composite pad would be needed for 4 with a maximum displacement of 0.10 to 0.16mm. The study had shown that vibration effects could be successfully monitored on factory floors through the vibration analyzer application, thus, minimizing harzardous effects on factory workers and facilties.
