Resumen en español

En el presente trabajo, se desarrolla un prototipo de monitor de vibraciones de bajo costo para maquinas de proceso. Este desarrollo incluye el diseño de electrónica de acondicionamiento de señales y la programación de un software capaz de detectar fallas incipientes en dichas maquinas en forma automática y en línea. El prototipo se ensayo en un banco experimental, simulando fallas y comprobando la detección y diagnostico de la anomalía. Se comprobó que el software es capaz de diagnosticar fallas o condiciones no deseables que generan fallas a futuro de forma automática en maquinas con velocidad de giro de 25Hz. Dentro de estas situaciones se destacan: desbalanceo, desalineamiento, golpes y alojamiento. Además, se contrasta el prototipo desarrollado con un sistema de referencia para poder determinar cuan confiable es el prototipo. Se encontró que el prototipo presenta un error relativo al sistema de referencia del 3% en la medición de la raíz del valor medio cuadrático de la velocidad y un error absoluto de 0;06mm=s en la medición de las amplitudes de picos en el espectro de frecuencias. Estos errores se consideran aceptables en base a dos criterios definidos en relación con la norma ISO 20816:1 [7]. Finalmente, se efectúa un análisis de costos para evaluar la conveniencia del desarrollo de un dispositivo de este tipo.

Resumen en inglés

This work consists in the development of a prototype for a low-cost vibration condition monitor for process machines. This development includes the design of electronics for signal conditioning and programming software capable of detecting incipient faults in the aforementioned machines. The program should be able to do this automatically and in real time. The prototype was bench-tested using experimentally simulated faults and verifying that the system detects and diagnoses the anomaly correctly. The software was determined capable of diagnosing faults or undesireable operating conditions that lead to future faults in machines with operating speeds of 25Hz. Among these conditions are: unbalance, misalignment, shocks and mechanical looseness. This prototype is then tested against a reference system so as to quantitatively evaluate its reliability. It was found that the prototype presents a relative error of 3% in terms of the v_rms value and an absolute error of 0:06mm=s peak-amplitude measurements. These errors are considered acceptable using criteria based on the ISO 20816:1 standard [7]. Lastly, a cost analysis is carried out to determine the financial feasibility of the continued development of this system.
