摘要：针对低温微量超声雾化声学系统中的关键部件单波长超声雾化喷嘴进行研究。首先基于等效电路原理
和传输矩阵法分别建立了带中心孔换能器和带中心孔复合变幅杆的频率方程，并应用数学分析软件获得了准
确的数值解，实现了超声雾化喷嘴的全谐振。然后，对其进行有限元动力学分析和振动特性测试，结果表明二
者相对于设计频率 25 kHz 的偏差率在 0.6% 以内，且空载超声振幅达 13.5 µm。之后，应用流体仿真分析软件

Abstract: The single wavelength ultrasonic atomizing nozzle, which is the key component of cryogenic
minimum quantity ultrasonic atomization acoustic system, is studied. Firstly, based on the equivalent circuit
principle and transmission matrix method, the frequency equations of transducer with central hole and
composite horn with central hole are presented. The accurate numerical solution of the frequency equations is
obtained by using the mathematical analysis software, and the full resonance of the system is realized. Then,
the finite element dynamic analysis and vibration characteristics test of the ultrasonic atomizing nozzle are
carried out. The results show that the deviation rate between the two relative to the design frequency 25 kHz
is less than 0.6%, and the idle ultrasonic amplitude is 13.5 µm. After that, the flow field characteristics of the
grinding area are analyzed by using the fluid simulation analysis software. The results show that the cryogenic
minimum quantity ultrasonic atomization acoustic system may solve the generation of air vortex phenomenon
