SIMULATION OF BEARING VIBRATION UNDER COMMON FAILURE CONDITIONS FOR EDUCATIONAL PURPOSES

Abstract

There is a very extensive and complete theory about the analysis of vibration in bearings, which is usually taught in predictive maintenance courses but can be difficult to understand and interpret. The objective of the present article is to generate a mathematical model of vibration that is based on the operating conditions and the inherent properties of the bearings of a row of balls, and that allows to visualize in graphs of amplitude versus time and amplitude versus frequency when it has a common fault to be used in a didactic way, considering this common fault as a very small bite present in one of the components (external track, internal track, cage and balls) the same that when colliding with another part generates a vibration that has a characteristic spectrum.

Keywords: Mathematical modeling, bearing, vibration.
