摘　　要：文章研究以夹心式换能器为研究目标,获取其机电等效电路,然后分析共振、反共振频率,于是得到换能器的径向振动特征和尺寸之间的关系。并且使用有限元法仿真模拟换能器径向振动特性,计算共振和反共振频率。实验结果表面,计算结果比实际结果具有较好的吻合度。This paper studies the sandwich transducer as the research goal,obtains its electromechanical equivalent circuit,and then analyzes the resonance and anti-resonance frequencies,so the relationship between the radial vibration characteristics and the size of the transducer is obtained.And the finite element method is used to simulate the radial vibration characteristics of the transducer,and the resonance and anti-resonance frequencies are calculated.The experimental results show that the calculated results have a better agreement than the actual results.
