【摘要】：為了進一步優(yōu)化壓電薄膜傳感器的制備工藝,探究壓電薄膜傳感器在建筑工程領域的應用前景,采用流延工藝制備了碳納米管改性的0-3型壓電復合薄膜,并使用該薄膜制成了壓電復合薄膜傳感器,將制得的壓電薄膜傳感器和傳統(tǒng)的電阻式應變片同時貼在等強度懸臂鋼梁上,通過采用2組不同頻率的正弦荷載和1組隨機荷載對懸臂梁進行激勵,對比研究了壓電傳感器和應變片在動態(tài)荷載激勵下的響應。研究結果表明:壓電復合薄膜傳感器具有更快的反應能力和更高的靈敏度,壓電薄膜傳感器可以有效地對結構的應力和應變進行實時監(jiān)測。
[Abstract]:In order to optimize the fabrication process of piezoelectric film sensor and explore the application prospect of piezoelectric film sensor in the field of building engineering, the 0-3 type piezoelectric composite film modified by carbon nanotubes was prepared by casting process. The piezoelectric composite film sensor is fabricated by using the thin film. The piezoelectric film sensor and the traditional resistive strain gauge are attached to the cantilever steel beam of equal strength at the same time. Two groups of sinusoidal loads with different frequencies and one group of random loads were used to excite the cantilever beam. The responses of piezoelectric sensors and strain gauges under dynamic loads are compared. The results show that piezoelectric composite thin film sensors have faster response ability and higher sensitivity. Piezoelectric thin film sensor can effectively monitor the stress and strain of the structure in real time.
