Paper Abstract

Liquid damped fiber laser accelerometer (LD-FLA) was proposed and a kind of LD-FLA structure, of which damping liquid could be easily change, was designed to study its damping characteristic. The principles of a LD-FLA were analyzed comparing with a common FLA, which found that liquid damper could produce additional liquid pressures in vibration so that not only damping responses but sensitivities and frequency responses could be changed at the same time. Four double diaphragm-based LD-FLAs were manufactured and experiments under several kinds of damping liquids were carried out. The experimental results are close to the calculated values and verify the theoretical analysis on LDFLA. The theoretical model provides guidance for further research on damping characteristic.
