Aplicación de la lógica difusa para detección de defectos en rodamientos

Abstract

El presente proyecto se enmarca en el mantenimiento predictivo de elementos de mecánicos, más concretamente en rodamientos. Estos componentes suelen ser concebidos y diseñados dentro de una máquina para ser los primeros en fallar, debido a su bajo coste y fácil sustitución. Por ello es de vital importancia el conocimiento de sus estado, para predecir el buen funcionamiento de la máquina. El objetivo de este proyecto es detectar fallos con cierto nivel de incipiencia de rodamientos en servicio utilizando técnicas de mantenimiento predictivo. En primer lugar, se pretende realizar una comparación entre diferentes métodos de tratamiento de señales, con el objetivo de discernir cuál es el más adecuado para analizar señales de vibración de rodamientos con distintos modos de fallo (fallo en pista interna, en pista externa o en bolas). En este sentido, se comenzará estudiando la Transformada de Fourier (FT), para dar paso a la Transformada de Hilbert (HT), técnica que permite el tratamiento de señales no estacionarias. En un segundo término, se utilizarán estas señales tratadas para diseñar un sistema clasificador basado en lógica difusa o borrosa, que interprete las vibraciones de distintos rodamientos y que sea capaz de distinguir si nos encontramos ante un rodamiento: · Con fallo en bola. · Con fallo en la pista externa. · Con fallo en la pista interna. · Normal (en buen estado y sin defectos incipientes).
