“…During the finite element analysis, the nodes' displacement of the holes at the ends of the four piezoelectric transducers are constrained to 0 (as shown in the blue part of Figure 7). [18,[20][21][22][23] The flange nut generates clockwise elliptical motion in the order of (a), (b), (c), (d). As shown in Figure 2, when the driving voltages of the four piezoelectric transducers are in the initial phase (t = nT), transducers No.1 and No.3 will be respectively stretched and contracted to the maximum extent.…”

A resonant-type piezoelectric screw motor for one degree of freedom (1-DOF) positioning platform is proposed, fabricated, and investigated in this article. The motor comprises a driver and a screw rod. The driver is composed of four transducers, a nut seat, and a flange nut. The flange nut is bolted connected on the nut seat, and the four piezoelectric transducers are connected with the nut seat by right-angle flexible hinges. Each piezoelectric transducer comprises two piezoelectric stacks and one displacement amplifier. Driven by the four piezoelectric transducers, elliptical vibration is generated by the driver, which is used to actuate the screw rod to realize the linear movement. The driver is analyzed using the finite element analysis software ANSYS. The proposed motor and positioning platform prototype are manufactured, assembled, and tested. The performance of the developed piezoelectric screw motor shows its applicability and effectiveness for the 1-DOF positioning platform with a large force. Experiments demonstrate that the maximum velocity of this motor is 10.53 mm/s without mechanical load and the maximum output force of the platform can reach 17.19 N when the excitation voltage is 230 V p-p at 365 Hz.

“…It was found from the simulation that the oscillation of cylinder was enhanced significantly by rotation in flow direction, but the opposite phenomenon was observed in cross flow direction. As well as based on the piezoelectric theory, researchers also explored the theory and application of ultrasonic motor [44][45][46][47][48]. However, there is few research on wind energy harvesting under nonlinear magnetic force.…”

Vortex-induced vibration (VIV) is used by piezoelectric energy harvesters to generate electricity from wind and water flow. In this study, we introduce the nonlinear magnetic force into piezoelectric energy harvesters and develop a nonlinear monostable piezoelectric VIV transducer. We build a distributed-parameter model based on the Euler-Bernoulli beam theory and Kirchhof's law to analyze the dynamic responses of the magnetic-coupling piezoelectric energy harvester (MCPEH). Model results show that the performance of the MCPEH varies greatly with the increase of the load resistance and the length of the used PZT. There are two optimal resistance values for the MCPEH. When R<31.6 kΩ, both the external load resistance and the PZT length affect the maximum power output. The little optimum resistance value will dwindle with the increase of the PZT length, whereas the large optimum resistance value still fixes at 1.78 MΩ with the increase of the PZT length. Due to the resistive shunt damping effect and the kinetic energy of wind, the resonance domain becomes wider in these ranges of load resistance smaller than 31.6 kΩ and larger than 316 kΩ comparing that when the load resistance is larger than 31.6 kΩ and smaller than 316 kΩ. Besides, the performance is enhanced by the monostable nonlinear magnetic force, which can be improved by decreasing the value of the distance between moving magnets and fixed magnets. The energy harvester shows a maximum power output of 0.21 mW under excitation of wind velocity is 1.6 m/s when the cylindrical diameter is 20 mm, the PZT length is 30 mm and the load resistance is 0.5 MΩ.

“…Moreover, it produces noise during operations due to the low driving frequency. For instance, Liu et al proposed a two-dimensional linear piezoelectric stepping platform by applying longitudinal and bending deformation of a piezoelectric actuator [14]. This platform obtained a high resolution of 1 µm, while its output velocities under no-load condition were 101.7 µm/s and 124.2 µm/s in two directions.…”

Utilizing the inherent advantages of the piezoelectric driving technology, such as good adaptability to vacuum environment and no electromagnetic interference, a novel self-moving framed piezoelectric actuator is proposed, simulated, and tested in this study, holding a potential application for magnetic confinement fusion. Four piezoelectric composite beams form a framed piezoelectric actuator. Two orthogonal vibration modes are excited and coupled in the framed piezoelectric actuator, producing a microscopic elliptical motion at its driving feet. Due to the friction, the framed piezoelectric actuator can move on a rail, thereby constructing the railed carrying system. Numerical simulation is carried out to confirm the operation principle and to conduct the dimensional optimization of the proposed framed piezoelectric actuator. A prototype of the proposed framed piezoelectric actuator with a weight of 83.8 g is manufactured, assembled, and tested, to verify the piezoelectric actuation concept. The optimal driving frequency of 20.75 kHz is obtained for the proposed actuator prototype, and at the excitation voltage of 400 Vpp its maximum mean velocity of 384.9 mm/s is measured. Additionally, the maximum load weight to self-weight of the proposed actuator prototype reached up to 10.74 at the excitation voltage of 300 Vpp. These experimental results validate the feasibility of the piezoelectric actuation concept on the railed carrying system.
