Abstract:The principle of piezoelectric pump operation is analyzed. The cavity volume fluctuations of piezoelectric pump is studied. The deformation of piezoelectric actuator is calculated by means of FEM software. The result of the calculation is an approximate parabolic surface. The basic method of measurement and calculation of the cavity volume fluctuations is given on the base of the result. The measurement and the calculation are carried out in the same time.
Keywords:piezoelectric  pump    volume  fluctuations    FEM
