摘要

The valveless piezoelectric pump with Y-shape tubes(VPPYT) is a new type of piezoelectric pump,it is designed for blood or fluid transfusion in such areas as medical treatment,sanitation and health care,so its driver-the piezoelectric actuator should meet the needs of the medical environment.Then,theoretical analysis is applied on the actuator,and formulas for the calculation of inherent frequency & maximum displacement of the piezoelectric actuator are deduced,the correctness of theoretical analysis is proved thereafter.Finally,base on the theoretical analytical model,the effects of geometrical parameters and material characteristic parameters on the actuator performance have been investigated.The analytical results reveal that the diameter ratio and thickness ratio of PZT/base layer should be near 0.75 and smaller than 1.0 respectively.The research provides a good reference for optimizing the design and manufacture of other types of piezoelectric pump.
