Radiation and reflection acoustical fields of an annular phased array

  • 摘要: 研究了超声环形相控阵辐射声场和反射声场的基本特性。理论上详细分析了环形相控阵的阵元数目、环形阵半径、阵元间距、中心频率、焦点位置等因素对辐射声场的影响。实验上设计并制作了具有8个环的等面积环形相控阵列并进行了实验测量。通过理论和实验分析,研究了环形相控阵的辐射声场及在液固界面上的反射声场特性,取得了理论和实验相吻合的结果。
    Abstract: The characteristic of the radiation and reflection acoustical fields of an annular phased array is investigated. The effect of the array number, array radius, interelement spacing, centre frequency, focus position, and other parameters on the radiation acoustical field of the annular phased array is theoretically studied. In experiment, an annular transducer with 8 equal-area elements is designed and fabricated, and a series of experiment measurements are conducted. The radiation acoustical field and its reflection on a liquid-solid interface are theoretically and experimentally studied. The experimental result is in good agreement with the theoretical one.
