Abstract

Based on hydro-solid coupling theory

the cantilever valve piezoelectic pump was comprehensively analyzed

and its dynamic model was established. After analysis of the interactions between hydro-mass

output pressure

system damp and working frequency

it is concluded that the decrease of chamber height will enhance the working frequency and stabilization. Then the vibrator structure parameters were confirmed through computing the influence law between vibrator structure parameter and amount of deformation. The conclusions show that the best thickness ratio is from 0.45 to 0.55 and the best diameter ratio is 0.8 to 0.9 between piezoelectric ceramic layer and the metal plate layer

respectively. The influence of the output form on the output ability also be considered

the result shows that axial output is in favor of the enhamement the output ability of the pump.
