Abstract

The FBG accelerometer, due to its advantages such as high sensitivity, wide frequency response, immunity to electromagnetic interference, strong corrosion resistance, and miniaturization, has wide applications in engineering fields. Under the premise of ensuring the sensor’s quality factor (Q), this paper introduces an FBG accelerometer featuring a cantilever-hinge structure, which effectively reduces the design and manufacturing complexity of the accelerometer. The accelerometer model is established using vibration theory, with structural optimization and simulation conducted in MATLAB and ANSYS. The accelerometer’s performance was evaluated through experimental testing. The study indicates that the accelerometer’s resonance frequency is 510 Hz, with a smooth frequency response between 0.1 Hz and 150 Hz. Its sensitivity is 54.12 pm/g, while the cross-sensitivity is under 9.7 %. This study offers a new approach to optimizing FBG accelerometer design, facilitating its broader engineering applications.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
