摘要：In order to reduce the stiffness of the flexure hinges, a low-frequency fiber Bragg grating (FBG) accelerometer based on multi-stage flexure hinges is designed. According to the series–parallel connection theory of springs, the acceleration response and anti-interference characteristics of the accelerometer are experimentally studied. The experimental results shows that the accelerometer with multi-stage hinges has a wide flat frequency band and high sensitivity. The resonant frequency is 84.2 Hz, the response sensitivity of the external vibration signal is 927.21 pm/G in the range of 1–60 Hz and the lateral interference degree is 5.8 %. It shows that the acceleration sensing performance of the accelerometer is good. On this basis, changing the hinge radius, thickness or the size of the mass block can further expand the measurement range of the accelerometer, which is expected to be applied in the field of low-frequency oil and gas seismic exploration.
