A trapezoid-type stick–slip piezoelectric linear actuator using a right circular flexure hinge mechanism was proposed, designed, fabricated, and tested with the aim of accomplishing driving based on motion. The angle adjustment trapezoid beam used for generating lateral motion foot mechanism. method tuning discussed. Based finite-element method, proper obtained. analysis results proved that asymmetrical can increase static friction force in slow extension stage decrease kinetic quick...
A resonant/off-resonant hybrid excitation of a piezoelectric stick–slip actuator is proposed in this paper. It accomplished by resonant sinusoidal friction regulation wave (RSFR-wave) and an off-resonant saw-tooth (ORST-wave). The RSFR-wave applied to the rapid deformation stage ORST-wave. In stage, first-order longitudinal vibration mode stator can be obtained. By mode, kinetic between slider frictional rod obviously decreased utilizing ultrasonic reduction. backward displacement remarkably...
This paper presents a lever-type stick-slip piezoelectric actuator based on the lever amplification principle. The proposed can achieve large strokes, high velocity, and bidirectional actuation with single stack. finite element simulation of flexible hinge is performed, designed prototype tested. When voltage 100 Vp-p, maximum forward velocity 7.69 mm/s under symmetry 20%. reverse 7.12 80%. displacement deviation within 10 cycles 0.88 μm, load reach 105 g.
A symmetrical hybrid driving waveform (SHDW) is proposed in this paper, which includes a saw-tooth and sinusoidal friction regulation waveform, the applied to shrinkage period of waveform. In other words, SHDW can be achieved when symmetry method 50%. The effectively drive designed linear piezoelectric stick-slip actuator, motion direction also easily regulated. excitation principle actuator excited by explained detail. prototype fabricated experimental investigations characteristics are...
A high-thrust screw-type piezoelectric ultrasonic motor with a three-wavelength exciting mode is proposed in this paper. The mainly includes stator and screw output shaft, the composed of twelve rectangular plates hollow metal elastomer an internal thread. can be excited to generate combined micro vibration mode. With mode, traveling wave synthesized. used drive shaft by means frictional force between shaft. Rotary-linear motion achieved without any additional conversion mechanism. Large...
