Paper Abstract

Resonance frequency calculation of accelerometer based on equal strength cantilever beam by Rayleigh method has been proposed and experimentally demonstrated. The accelerometer is with a compact structure in which a short section of fiber stubs containing a fiber Bragg grating (FBG) is attached on the bisector of a equal strength cantilever beam. By comprehensive considering the mass of beam and the mass of the block together, resonance frequency of different accelerometer can be calculated more precisely, compared with the experimental results the maximum relative error is 7.2% over the low frequency range from 20 to 45 Hz.
