检测用圆锥声透镜换能器的研究
STUDY ON THE TRANSDUCER WITH CONICAL LENS FOR ULTRASONIC TESTING
【摘要】 通过数值计算和实际测量 ,研究圆锥声透镜聚焦换能器产生的声场 ,证实其能产生较细长的聚焦声束 ,且透镜形状参数对聚焦声场分布有明显影响。
【Abstract】 The sound fields generated by the transducers with conical acoustic lens were studied through numerical calculations and experiments. It was shown that a narrow sound beam over a longer axial range could be obtained by conical acoustic lens, and sound field characteristics were greatly affected by the shape parameters of the curved surface.
