Abstract: In the development of the inertial impact driving movement mechanism actuated by the multilayer piezoelectric actuator a new method to realize the intending movement of the mechanism by changing the pressure between the mechanism and the contact surface to change the friction in the different directions. The working principle of the piezoelectrically actuated movement mechanism was introduced and a prototype of linear precision mechanism was developed and its experiments on the movement velocity versus signal voltage and frequency were performed. The results show that the controlable positive linear movement of the mechanism is realized under the excitation of the symmetric square wave signals.
