Measurement of the Natural Frequency of Bench Drill Based on Fiber Bragg Grating
A new method for measuring the natural frequency of a complex structure using fiber Bragg grating (FBG) sensor is introduced. The FBG strain sensor is stuck on the surface of the drill block. The natural frequency of the drill is measured to be 23.9 Hz by monitoring the strain change caused by mechanical vibration. It matches the result achieved by ANSYS finite element analysis very well.
