“…Moreover, dynamic models with different configurations were established in studies of FHMs-PSSAs. In the process of dynamic modeling, the LuGre (Lund-Grenoble) dynamic friction model is usually used in the analyses of friction between the stator and the rotor (Le et al, 2019;Li et al, 2017aLi et al, , 2018aShao et al, 2019b;Wang et al, 2019aWang et al, , 2020a. Besides, as shown in Figure 9(e), Lu et al (2020a) established a dynamic model of the designed FHMs-PSSA based on the method of dimensionality reduction (MDR), which reduces the amount of calculation so that it could calculate displacement curves and load characteristics in the dynamic simulation of the system quickly.…”

Piezoelectric stick-slip actuators (PSSAs) are famous for ultimate working condition adaptability, simple structure, and positioning accuracy. To meet the demand of industrial application, lots of PSSAs designed with flexure hinge mechanisms (FHMs-PSSAs) have been developed to realize the requirements of translational motion, rotational motion, multi-degree-of-freedom (multi-DOF) motion. The output performance of the FHMs-PSSAs has been greatly improved, including load capacity, speed, and accuracy; moreover, some approaches to solve the problem of the backward motion are provided as well. In this work, the working principle of FHMs-PSSAs is introduced, and the excitation signals applicable to FHMs-PSSAs are summarized. Based on the current research and development status, the progress of structure design of FHMs-PSSAs is introduced in accordance with translatory FHMs-PSSAs, rotary FHMs-PSSAs, and multi-DOF FHMs-PSSAs. Additionally, the developed analysis methods and design schemes to improve the performance are introduced, including theoretical analysis methods, consistency scheme of forward and reverse performance, suppression scheme of the backward motion, and improvement scheme of positioning accuracy. The significance of this work can be regarded as a further supplement to the previous review articles on the PSSAs, which will provide a reference and guidance for the future development of FHMs-PSSAs.

“…This article proposes a compact bidirectional motion piezoelectric actuator, which uses coupled asymmetrical flexure hinge mechanisms and symmetrical indenter to generate controllable tangential displacement. Compared with the previous actuators (Cheng et al, 2017a; Li et al, 2018b; Qin et al, 2019; Wang et al, 2019a; Wen et al, 2019), due to the larger tangential displacement, larger static friction force, and smaller kinetic friction force, the output performances of the proposed actuator have a considerable improvement, such as the output velocity, load, and efficiency. The MDR friction model is introduced, including the normal contacts model and tangential contacts with friction, and experiments are demonstrated to prove the effectiveness of the proposed frictional model.…”

A stick-slip piezoelectric actuator with bidirectional motion is proposed and measured, which uses coupled asymmetrical flexure hinge mechanisms and symmetrical indenter to generate controllable tangential displacement. The operating principle of the proposed stick-slip actuator is illustrated, and the normal force variation between the stator and slider is analyzed. A dynamic model based on the method of dimensionality reduction is established to simulate the displacement and load capacity. In order to obtain improved actuator properties, the design rules of the coupled flexure hinge mechanisms are discussed, and the tangential and normal displacements of the indenter are investigated by the finite element method. A prototype is fabricated, and the experiment investigation of the actuator characteristics is presented. Testing results indicate that the actuator achieves the maximum output velocity of 10.14 mm/s and its maximum load reaches 1.5 N under a voltage of 100 Vp–p and a frequency of 850 Hz in the positive x-direction. The maximum efficiency of the actuator is 0.57% with a load of 90 g, a locking force of 5 N, and the actuated velocity of 5.48 mm/s. In addition, experimental results confirm the feasibility of the presented model by comparing numerical simulation results.

A piezoelectric actuator (PEA) has the characteristics of high control precision and no electromagnetic interference. To improve the degree of freedom (DOF) to adapt to more working scenes, a piezoelectric–electromagnetic hybrid-driven two-DOF actuator is proposed. The PEA adopts the composite structure of the lever amplification mechanism and triangular amplification mechanism. The structure effectively amplifies the output displacement of the piezoelectric stack and increases the clamping force between the driving foot and the mover. The electromagnetic actuator (EMA) adopts a multi-stage fractional slot concentrated winding permanent magnet synchronous actuator, which can better match the characteristics of PEA. The structure and working principle of the actuator are introduced, the dynamic analysis is carried out, and the factors affecting the clamping force are obtained. At the same time, the air gap magnetic field is analyzed, and the structural size of the actuator is optimized. The experiment shows that the maximum driving speed can reach 348 mm/s, the load capacity is 3 kg, the optimal initial rotor angle is 49°, the maximum torque is 2.9 N·m and the maximum speed is 9 rad/s, which proves the stability and feasibility of the actuator.
