【Abstract】 Based on the forced vibration analysis of the composite piezoelectric vibrator actuated by sinusoidal voltage,the deformation solution and resonance frequency equation were obtained for simple supported edge.A formula for the enclosed volume of the deformed vibrator,namely,the pump chamber of a valve less piezoelectric pump was derived by Rayleigh Ritz method.The relationship between the pump chamber and the maximum deformation of the vibrator was analyzed.The simplified expression of the pump chamber according to the relationship.更多还原
