Embodiment Construction
[0046] A preferred embodiment of the present invention is described as follows in conjunction with accompanying drawing:
[0047] See figure 1 , the curved surface vibration deformation detection system, including a vibrating surface ①, a signal generator ④ (model: SFG-2110 production unit: Taiwan Good Inst), a DC power supply ③, a vibration exciter ⑤ (model: JZK —10 Production unit: Jiangsu Lianeng Electronics Co., Ltd.), implanted FBG sensor ②, a fiber grating demodulator ⑥ (model: FONT-2201A production unit: Shanghai Zishan Optoelectronics Technology Co., Ltd.), a graphics processing computer ⑦, a monitor ⑧.
[0048] The DC power supply ③, the exciter ⑤, and the signal generator ④ make the curved surface ① produce various vibration modes; the FBG sensor ② is implanted according to the change of the surface stress and its reflection wavelength changes; the FBG demodulator ⑥ detects the change of the wavelength, The wavelength change is transmitted to the graphics processor...
