Abstract
Recently it has been reported the use of non-invasive methods for the identification and monitoring of vibrational parameters in rotodynamic systems, such as aircraft engines, which require the implementation of innovative detection systems, such as fiber optic sensors, which overcome deficiencies of adaptability to adverse environments such as intense magnetic fields and the impossibility of performing a distributed detection of vibrations, limitations present in the sensors conventionally based on capacitive or piezoelectric principles. Therefore, in the present study, through the use of an experimental platform for dynamic analysis, the best proposal of an instrumental system based on fiber optic sensors with Bragg gratings was selected for its use in vibrational measurement and analysis, through the theoretical study of the different approaches to vibrational analysis using fiber optic sensors with Bragg gratings. The analysis of the results of the study presents a justification of the type of instrumental proposal selected from the characteristics provided by the experimental platform. In addition, the experimental proposal will be implemented in the future and may contribute to the development of other vibrational studies.
