Axisymmetric Motion of Radially Polarized Piezoelectric Cylinders Used in Ink Jet Printing

摘要

An analysis of the low frequency response of piezoelectric squeeze tubes used in drop-on-demand ink jet printing is carried out. The displacements at inner and outer boundaries are determined as a function of voltage and fluid pressure. The results are used to obtain fluid pressure per applied voltage as a function of inner and outer radius. Numerical computations are carried out for PZT-5H, and results are presented in graphical form which can be used to optimize design dimensions. The effect of finite electrode thickness is also studied.
