正交各向异性压电复合材料（OPCM）传感器具有高灵敏度，可用于结构健康监测。为了减小侧向反射波的干扰，获得宽频带、高聚焦能量的反射波信号，在前人研究的基础上，研究了一种新型的光学PCM聚焦换能器。通过仿真研究了OPCM聚焦换能器与PZT换能器的优越性和声场特性，并通过实验验证了应力对比结果。研究表明，聚焦换能器在工程结构检测中的盲区约为距检测表面1.5mm，大大增加了工程结构损伤检测中获取高能量、高信噪比反射波信号的容易程度。
The advanced orthotropic piezoelectric composite material (OPCM) sensor can be used in structural health monitoring with a highly sensitive performance. In order to reduce the interference of lateral reflected waves and obtain the reflected wave signal with wide frequency bandwidth and high focusing energy, a new type of OPCM focusing transducer was studied based on the previous research of OPCM. Compared with the PZT transducer, the superiority and the acoustic field characteristics of the OPCM focusing transducer are studied by simulation, and the stress comparison results are verified by experiments. It is shown that the blind area of the focusing transducer in engineering structure detection is about 1.5 mm from the detection surface, which greatly increases the ease of obtaining reflected wave signals with high energy and high signal-to-noise ratio in engineering structure damage detection.
