Based on the conventional 1-3-2 type piezoelectric composite material, an improved 1-3-2 type piezoelectric material is proposed to enhance the electromechanical coupling coefficient and receiving sensitivity of the piezoelectric transducer. The effects of different spacings on the re...
该文在传统型1-3-2压电复合材料的基础上提出了一种改进型1-3-2压电材料,提高了压电换能器的机电耦合系数和换能器的接收灵敏度。通过有限元仿真分析了不同间距对改进型1-3-2压电材料敏感元件的谐振频率、反谐振频率及机电耦合系数的影响,并与传统1-3-2型压电复合材料进行了对比。结果表明,与传统型1-3-2...
