This paper presents a new type metalpiezoelectric composite tube actuator to meet the requirements of micro vibration control and vibration isolation system for the shift, driving force and other performance requirements of piezoelectric actuator.The tubular piezoelectric actuators are bonded to a metal tube,when the piezoelectric tube is subjected to the external excitation voltage effect,it will produce the expansion strain in the axial direction,so that the metal tube in the axial direction will produce displacement and driving force. Firstly, the static actuation performance of the metalpiezoelectric actuator is analyzed,the results show that the metalpiezoelectric actuator has moderate displacement and driving force; at the same time,using the finite element method to validate the above result.For a certain metalpiezoelectric composite pipe, the strain obtained by theoretical calculation formula is 0.912×10-5,and the strain obtained by the finite element method is 0.925×10-5.It proves the effectiveness and correctness of the theoretical calculation formula;Finally,the design and fabrication of a copper piezoelectric composite actuator is carried out.
