Resumo: | The use of vibration monitors is a well-established practice in industrial maintenance, usually vibration sensors are positioned at specific points on the monitored machinery and data are continuously collected to feed a machine operating health control system. Nevertheless, the technology for obtaining the signal, its treatment and analysis is generally expensive, and the financial return is not evident, which justifies the development of low-cost alternatives technologies. In this work was performed an analysis of the responses of two Micro-Electro-Mechanical accelerometers, models ADXL345 and MPU6050, exposed to a low intensity random signal and standard operating frequency. The objective of the analysis was to verify the capacity of these devices to be used as mechanical vibration sensors for rotating machines. For this purpose, offset shift analyzes of the sensors due to the Earth's gravitational field were performed, as well as vibrational spectrum and rectification errors analysis under multiple conditions. The data pointed to a greater uniformity of the MPU6050 response, while several behavioral anomalies were seen in the ADXL345, when these sensors are exposed to the same mechanical signal. The qualitative and quantitative behavior of MPU6050 rectification error was consistent with reported in the literature. It was noted that the methodology used can profile the behavior of sensors, however, it is not sufficient to safely justify the inaccuracies, requiring that the tests be performed on a statistically representative number of sensors from different manufacturers and batches. |

Sin embargo, la tecnología para obtener la señal, procesarla y analizarla es generalmente costosa y la rentabilidad económica no es evidente, lo que justifica el desarrollo de tecnologías alternativas de bajo costo. En este trabajo se realizó un análisis de las respuestas de dos acelerómetros microelectromecánicos, modelos ADXL345 y MPU6050, expuestos a una señal aleatoria de baja intensidad y frecuencia de operación estándar. El objetivo del análisis fue verificar la capacidad de estos dispositivos para ser utilizados como sensores mecánicos de vibración en máquinas rotativas. Para ello, se realizaron análisis de offset shift de los sensores debido al campo gravitacional terrestre, así como análisis de espectro vibratorio y errores de rectificación. Los datos apuntaban a una mayor uniformidad de la respuesta del MPU6050, mientras que se observaron varias anomalías de comportamiento en el ADXL345, cuando estos sensores están expuestos a la misma señal mecánica. El comportamiento cualitativo y cuantitativo del error de rectificación del MPU6050 fue consistente con lo reportado en la literatura. También se observó que la metodología utilizada puede perfilar el comportamiento de los sensores, sin embargo, no es suficiente para justificar con seguridad las inexactitudes, requiriendo que las pruebas se realicen en un número estadísticamente representativo de sensores de diferentes fabricantes y lotes.O uso de monitores de vibração é uma prática bem estabelecida na manutenção industrial, geralmente sensores de vibração são posicionados em pontos específicos do maquinário monitorado e dados são continuamente coletados para alimentar um sistema de controle de integridade operacional. No entanto, a tecnologia de obtenção do sinal, tratamento e análise geralmente é cara e o retorno financeiro não evidente, o que justifica o desenvolvimento de tecnologias alternativas de baixo custo. Neste trabalho foi realizada uma análise das respostas de dois acelerômetros microeletromecânicos, modelos ADXL345 e MPU6050, expostos a um sinal aleatório de baixa intensidade e frequência de operação padrão. O objetivo da análise foi verificar a capacidade desses dispositivos em serem utilizados como sensores mecânicos de vibração em máquinas rotativas. Para tanto, foram realizadas análises de offset shift dos sensores devido ao campo gravitacional terrestre, bem como análises de espectro vibracional e erros de retificação. Os dados apontaram para uma maior uniformidade da resposta do MPU6050, enquanto várias anomalias comportamentais foram observadas no ADXL345, quando esses sensores são expostos ao mesmo sinal mecânico. O comportamento qualitativo e quantitativo do erro de retificação MPU6050 foi consistente com o relatado na literatura. Observou-se ainda que a metodologia utilizada pode traçar o perfil do comportamento dos sensores, porém, não é suficiente para justificar com segurança as imprecisões, exigindo que os testes sejam realizados em um número estatisticamente representativo de sensores de diferentes fabricantes e lotes.Research, Society and Development2021-11-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2308210.33448/rsd-v10i15.23082Research, Society and Development; Vol. 10 No. 15; e286101523082Research, Society and Development; Vol. 10 Núm. 15; e286101523082Research, Society and Development; v. 10 n. 15; e2861015230822525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/23082/20342Copyright (c) 2021 João Victor Oliveira Rodrigues; Marcos Paulo Gonçalves Pedroso; Flávio Fernandes Barbosa Silva; Reginaldo Gonçalves Leão Juniorhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRodrigues, João Victor Oliveira Pedroso, Marcos Paulo GonçalvesBarbosa Silva, Flávio Fernandes Leão Junior, Reginaldo Gonçalves2021-12-06T10:13:53Zoai:ojs.pkp.sfu.ca:article/23082Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:42:03.766008Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
