The experimental results show that the amplitude of vibration decreases and the resonance peak moves to higher frequency as the strength of electric field increases.
The numerical simulation and test result of the experimental sample indicate that the system can control both vibration and shock and it also has a wider frequency response range, a greater displacement response range and a satisfying vibration isolation ratio without resonance peak.
The bending of simple supported beam make the resonance peak wavelength of each mode of TFBG shift and resonance peak amplitude unchangeableness.
Larger height corresponds to smaller LSP resonance wavelength and narrower resonance peak.
