“…Dual piezoelectric actuators for the traveling wave ultrasonic motor are presented in [10]; this motor uses dual piezoelectric patches bonded on the beam structure but it uses teeth also to generate this traveling wave using the two mode excitation method.…”

In this paper, the operation principles of a traveling wave piezoelectric beam robot are presented. A prototype consisting of an aluminum beam structure, with two non-collocated piezoelectric patches bonded on its surface, was fabricated and tested to demonstrate the generation of a traveling wave on the beam based on the one mode excitation and the two mode excitation operation principles for propulsion. A numerical model was developed and used to study and optimize the generated motion of the piezoelectric beam robot. Experimental characterization of the robot for the two types of operation has been carried out, a comparison between them is made and results are given in this paper.

“…But, the structures of these two traveling wave USLMs made it difficult to reduce the volume [4]. In recent years, a traveling wave USLM using two multilayered piezoelectric ceramic (PZT) elements between two parallel bending bars, a traveling wave USLM with bimorph transducers and a traveling wave USLM with dual piezoelectric actuators have been developed [5,6,7]. These three traveling wave USLMs realized the traveling wave drive in USLMs.…”

Ultrasonic linear motor, Piezoelectricity, Rectangular vibrator, Traveling wave Abstract. With the aim of realizing quasi-traveling wave drive in ultrasonic linear micro motors, a novel quasi-traveling wave ultrasonic linear motor using a ring type rectangular vibrator with the sizes of 39mm×6mm×12.7mm is proposed. The quasi-traveling wave is excited and propagates along the ring type rectangular vibrator depending on the superposition of two orthogonal flexural-vibration modes with a spatial phase shift of 90 degrees. 7 piezoelectric ceramic elements are used to excite two working modes of the vibrator. The vibrator structure was designed and eigenfrequency degeneration was realized by Finite Element Analysis (FEA) method. The modal test shows that the design scheme was tenable. The excitation and propagation of quasi-traveling wave were proved by laser vibration test. The trial motor gave a maximum driving velocity of 162.5mm/s and a maximum load of 8.5N, while the excitation frequency was 66 KHz and voltage was 160Vpp.

“…[4] built the first prototype in 1985 with a vibrator-absorber system. Several other articles reported the application of linear traveling wave motor based on the same principle of rotary traveling wave motor by superposing orthogonal standing waves [5], [6]. But the edge reflexion is still a problem and damping material is needed at the boundaries to prevent from the reflection [7].…”

-Traveling wave generation in a ring type stator has been studied. The basic working principle to create traveling wave has been modelled by the superposition of two orthogonal standing waves. Theoretical analysis shows that the length to radius ratio affects the frequency gap between two pseudo orthogonal modes used to create traveling wave. FEM simulation is then discussed and applied to validate the analytical model. At last, a possible optimal solution is reported with FEM verification.
