| 摘 要： | 提出了由纵向振动系统与弯曲振动圆盘组成的纵弯转换超声振动雾化系统的新型结构。通过理论分析和有限元分析，揭示了由换能器、变幅杆与工具组成的振动系统的各种谐振状态特性, 研究了系统的谐振设计方法。分析表明：新型雾化振动系统工作于负载谐振模式，其谐振频率主要取决于纵振动系统的结构，弯曲振动薄圆盘相当于系统的负载。当弯曲振动圆盘谐振频率与系统的谐振频率越接近时，系统的输出振幅越大。通过实验证明了理论研究正确性。

| Abstract: | The new ultrasonic vibration mist system composed of longitudinal vibration transducer and flexural vibration disc is proposed in this paper. The resonance property and the design method of the new system are got through theoretical and FEM analysis. It was proved by experiment that the new system mainly works in loading resonance state. The resonance frequency of the new system is mostly depended on the structure of transducer. The output amplitude of the new system increases with the approaching of the resonance frequency between the longitudinal vibration system and the flexural vibration disc. |
