矩形压电片对Lamb波传感的方向性研究
Study on Directivity of Rectangular Piezoelectric Sensors Sensing Lamb Waves
摘要
Abstract
Rectangular piezoelectric sensors are widely used as Lamb waves sensors and actuators. The function of sensitivity of rectangular piezoelectric sensors sensing Lamb waves (A0 mode) is deduced, and the results are testified by experiments. Results show that rectangular piezoelectric sensors have high directivity to sense Lamb waves. The amplitude of response gets its maximum when Lamb waves are in line with sensor lengthwise direction, the amplitude will turn smaller as the propagating angle increasing and the amplitude of response gets its minimum when Lamb waves are perpendicular to sensor lengthwise direction.关键词
