Abstract
The injection characteristics of a piezoelectric micro-jet are analyzed in this paper by numerical simulations and experiments. The effect of acoustic-structure interaction on the working frequency of the vibrator are analyzed by simulations and experiments. The vibration statuses of the vibrator are given when the cavity is filled with liquid or air. A simulation method for analyzing the frequency response characteristics of micro-jet is proposed, and the influences of the shell materials on the nozzle pressure are analyzed. In order to improve the injection performance, the recommended working frequency and adjustment methods of the excitations are given when selecting different shell materials. Experiments are carried out and the actual injection performance is obtained which prove the numerical simulation method can be effective.
