Abstract

Vibration signals contain a lot of information that reflects the working status of the mechanical arms, which is of vital significance for vibration suppression monitoring and fault diagnosis. Hence, it is meaningful to develop a new type of sensor that detects vibration signals accurately and conveniently. Fiber Bragg Grating (FBG) sensors are increasingly applied because of their many advantages like high sensitivity, low weight and small size, anti-electromagnetic interference and easy multiplexing, etc. In this work, the model of an FBG accelerometer has been designed which contains a rhombus hollow lattice cylinder. Finite Element Simulations was used to analyze dynamic behavior of the sensor with a simulated resonance frequency of 297 Hz and good frequency response range from 10 to 100 Hz. Theoretical sensitivity of the sensor of was 71.56 pm/g. The sensor is supposed to be used for vibration monitoring of low frequency of mechanical arms.
