Simulating on a New Elastic Element of FBG Accelerometer
A new elastic element of fiber Bragg grating(FBG) accelerometer which is four peripheral clamped trapezoidal beams is developed. The simulation of this elastic element with ANSYS is carried out. From the results, it shows that as an elastic element, four beams have the advantages of lower cross-axis sensitivity which is smaller than 52 dB and nearly uniform strain along the grating area. In addition, its work frequency is higher than the single beam constituting four beams. This kind of elastic element not only can be used with fiber Bragg grating accelerometer, but also other types of sensors.
