Abstract
Rolling bearing failures are frequent in the routine operation of industrial equipments. These failures often occur unexpectedly, causing unscheduled interruption in production and, consequently, losses. One way to inspect the development of these failures is through predictive analysis of equipment such as sensitive inspection, boroscopy, lubricant analysis, thermography and vibration analysis, the latter being frequently used in monitoring the rating life of the equipment. Finding a mathematical model that provides understanding of how bearing failure evolves is very useful, therefore, through the analysis of the vibration spectrum, the severity of the failure in the component can be understood and maintenance can be scheduled in advance. This study presents the dynamic simulation of a faulty roller bearing mathematical model with 2 degrees of freedom for evaluating the behavior of the response in time and frequency, comparing a healthy and a roller bearing with surface damage. The mathematical model was implemented in the Octave software and the results obtained in numerical simulation were compared with the literature results. The impacts on the frequency response were evaluated by varying theses parameters: number of rolling elements, length and depth of the defect and the load applied to the roller bearing
