摘要
文中将超声相控线阵换能器视为复合材料,将复合材料力学与声学理论相结合,通过计算超声相控线阵换能器模型的等效力学参数,推导出了线阵换能器声波方程的解;并依据声波方程的解进一步得出了超声相控线阵换能器参数对线阵换能器接收灵敏度的影响规律。
Based on mechanics of composite materials and acoustic theory, equivalent mechanical parameters of linear ultrasonic phased array transducer are calculated by regarding linear ultrasonic phased array transducer as composite material. Then the solution of acoustic wave equation of ultrasonic linear phased array transducer is derived. Based on it, the influence rules of parameters of linear phased array transducer on receiving sensitivity are obtained.
