Abstract: | The paper covers the research and development of piezoelectric traveling wave actuators using different types of the waveguides.
The introduced piezoelectric actuators can be characterized by specific areas of application, different resolution, and torque. All
presented actuators are ultrasonic resonant devices and theywere developed to increase amplitudes of the travelingwave oscillations
of the contact surface.Three different waveguides are introduced, that is, symmetrical, asymmetrical, and cone type waveguide. A
piezoelectric ring with the sectioned electrodes is used to excite traveling wave oscillations for all actuators. Operating principle,
electrode pattern, and excitation regimes of piezoelectric actuators are described. A numerical modelling of the actuators was
performed to validate the operating principle and to calculate trajectories of the contact points motion. Prototype actuators were
made and experimental study was performed.The results of numerical and experimental analysis are discussed. |
