The vibration property and design of ultrasonic mist system based on longitudinal-flexural vibration conversion
In this paper, the new ultrasonic vibration focusing system composed of longitudinal vibration transducer and flexural vibration spherical shell is proposed based on the principle of longitudinal-flexural vibration conversion. The resonance property of the new system is analyzed by means of plate-shell theory, FEM method and experiments. It is proved that the new system has two resonance patterns named as complete resonance and incomplete resonance. In the incomplete resonance pattern, the system can work in the condition of either integral resonance or local resonance. The system design method is proposed for different working conditions based on the research which is of important meaning for the application of the new focusing system.
