Integration of a Prognosis Model of a Rotating Microwave Oven Guidance System Subject to Linear Degradation

Abstract

In this article, we propose a prognosis model for estimating the remaining useful life (RUL) before the failure of a wear bearing to guide rotating trees in microwaves, in the company called (COSUMAR-Morocco). It is a matter of establishing a model of the degradation envisaged (deterioration by phenomenon of wear) during the favorable mission to the decrease of the reliability over time. The proposed approach is based mainly on the model of behavior of the system under predefined working conditions (Evolution of the degradation). This work consists in establishing an adaptive model for this phenomenon, an empirical law envisaged, a degradation based on the computation of the rate of wear by the formula of ARCHARD. This model helps us predict the remaining useful life (RUL) of the wear bearing before failure, the main objective of this law is to help the maintenance manager to take the action before the failure.
