Optimal placement of piezoelectric torsional actuator based on genetic algorithm;

A piezoelectric torsional actuator was bonded onto the root of the flexible bar to suppress the torsional vibration of the flexible bar,and another piezoelectric shear actuator was bonded onto the root of the flexible beam to sup.

A smart bar is proposed,which is composed of a thin-walled bar,a piezoelectric torsional actuator and a piezoelectric sensor.

Electromechanical response of a functionally gradient piezoelectric actuator based on PZT ceramics at resonance condition;

Close-loop control of inchworm-type piezoelectric actuator;

Disk-pivot structure micro piezoelectric actuator with bimorph;

Based on the study of kinds of nonlinear models, Maxwell hysteresis model of piezoelectric actuators was established.

Precision positioning, microdisplacement and microforce operation are realized by means of the piezoelectric actuators on the flexible manipulators.

At the same time,the way of controlling piezoelectric actuators is simple and easy.

Harmonic piezomotor has the wave generator which contains fixed piezoactuator and displacement amplifier, by means of controlling the piezoactuator deformation periodically and amplifying its displacement, the flexspline generates periodic deformation.

This paper introduces the principle,characteristics and displacement performance of piezoactuator.
