【摘要】：为了进一步优化压电薄膜传感器的制备工艺,探究压电薄膜传感器在建筑工程领域的应用前景,采用流延工艺制备了碳纳米管改性的0-3型压电复合薄膜,并使用该薄膜制成了压电复合薄膜传感器,将制得的压电薄膜传感器和传统的电阻式应变片同时贴在等强度悬臂钢梁上,通过采用2组不同频率的正弦荷载和1组随机荷载对悬臂梁进行激励,对比研究了压电传感器和应变片在动态荷载激励下的响应。研究结果表明:压电复合薄膜传感器具有更快的反应能力和更高的灵敏度,压电薄膜传感器可以有效地对结构的应力和应变进行实时监测。
[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.
