Abstract

This paper focus on the strain characteristic of the fiber-optic flexural disk accelerometer based on the multilayer sensing fiber coils. The strain state is analyzed in theory, and by using the simulation software, we built the simulation model and obtain the strain distribution of the multilayer sensing fiber coils in different bonding position of the flexural disk. The strain theoretical model agrees well with the strain distribution obtained by the simulation model. According to the results, a flexural disk accelerometer is produced. Experiment results show that the phase sensitivity is 6814rad/g, which is equivalent to the acceleration sensitivity of 15ng/Hz^1/2.
