Abstract A screw-type piezoelectric actuator based on the bidirectional bending vibration of piezoelectric metal compound beam was proposed, where each piezoelectric transducer worked on Kt mode. The form of actuator structure was determined according to the first order bending mode of beam in space preliminarily; Secondly, the influence of stator’s material and structure parameter on natural frequency and end surface amplitude was analyzed through ANSYS software, the influence of material parameter E/on the first order natural frequency of stator was especially discussed; Then, the structure dimension of actuator was determined according to the analysis results, and the prototype of actuator was made; Finally, the main output characteristics of prototype were tested through corresponding experimental system. The results indicate that the actuator responds sensitively with the start-stop time in about 20ms, the optimum excitation frequency is approximately 15.8KHz, the maximum no-load speed and output axial force are 1.146mm/s and 2.5N separately under Vpp=300V.
