摘要
利用有限元和边界元耦合的方法对涂环氧树脂后的压电陶瓷凸球面换能器进行了指向性仿真计算,发现这种形式的换能器具有较宽的指向性开角。实验测量结果证明了上述结论。
The finite element method and the boundary element method are applied to the transducer directivity analysis after coating Epoxy Resin onto the surface of a protuberant spherical piezoelectric transducer. Calculation using software shows that such transducer indeed possesses broader directivity. Experimental result verifies the simulation.
