“…Taking a simple FHMs-PSSA as the research object, Shao et al (2019b) stated that the step displacement mainly depended on the excitation signal’s voltage and the friction between the stator and the rotor. As shown in Figure 7(f), Ding et al (2019) designed a rotary FHMs-PSSA with a regular octagonal mechanism to suppress the backward motion; through the cooperation of four compliant feet in the driving process, the static friction in the stick phase could be increased, and the dynamic friction in the slip phase could be reduced. However, the above-mentioned rotary actuators all adopted bearings to change from translational motion to rotational motion, and the nonlinear trend of displacement curve in the step process caused by the gap between bearings was inevitable (Huang et al, 2016); to avoid the error, Le et al (2019) and Wang et al (2020a) proposed FHMs-PSSAs with self-centering function based on flexure hinge structure, as shown in Figure 7(g).…”

“…According to the statistical analyses of published literatures related to FHMs-PSSAs, the pseudo-rigid body method (Ding et al, 2019; Wang et al, 2017b) and the elastic beam method (Li et al, 2017a; Xu et al, 2020) are commonly used in the analyses of the flexure hinge mechanism. The pseudo-rigid-body method assumes that the flexure hinge can only move in one degree of freedom, while ignoring the elastic deformation at the thin flexure hinge.…”

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.

The piezoelectric stick-slip stage is very important in industrial manufacturing and precision machining. However, due to the stick-slip principle, it is inevitable to produce backward motion, which leads to a decrease in precision and efficiency. A novel smooth-drive scheme for piezoelectric stage is proposed by coupling stick-slip motion and inertial impact in this paper. In the coupling counteract phase, the sliding friction force of stick-slip driving mechanism (SDM) is counteract by the impact force of inertial impact driving mechanism (IDM), thus eliminating the backward motion and realizing the smooth driving of the stage. The feasibility of the stage is analyzed by theoretical calculation and transient dynamics simulation. In addition, the designed stage is fabricated and conducted a complete set of experimental tests. The external dimensions of the stage is 45 mm (L) × 24 mm (W) × 22 mm (H), and the mass is 84 g. Experimental results show that the piezoelectric stage can not only achieve smooth driving, but also actively adjust the output smoothness by adjusting the excitation voltage of PZT I and PZT II. The linear fitting correlation coefficient R2 of the displacement curve can reach above 0.999, and it still keeps good smoothness at 200 Hz. The maximum vertical mass load of the stage is 4 kg, which is about 47 times the mass of the stage, and the resolution of stick-slip state is about 85 nm. The scheme has positive reference value in the field of stable and accurate positioning.

“…It is noted that most of the previously developed stickslip piezoelectric actuators are designed to achieve the linear motion [18][19][20][21][22][23][24], and the design of rotary actuators is relatively less reported. Currently, only a few studies focused on the rotary actuators [25][26][27]. For example, Li et al [25] designed a stick-slip piezoelectric rotary actuator by using a bridge-type flexure hinge mechanism.…”

Although the stick-slip piezoelectric linear actuators have been widely investigated, the design of stick-slip piezoelectric rotary actuators is rarely reported and the corresponding output performances could be further improved. In this study, by employing a centrosymmetric flexure hinge mechanism, a novel stick-slip piezoelectric rotary actuator was designed. Its structure and working processes were addressed in detail, and the main structural parameters of the centrosymmetric flexure hinge mechanism were designed by the finite-element method. After that, a prototype was fabricated and a series of experiments were performed to test its output performances. The experimental results showed that under various driving voltages, the actuator could output stable angular displacement, and with increase in the driving voltage, the angular speed tended to linearly increase. Under the driving voltage of 100 V and driving frequency of 600 Hz, the actuator reached a maximum angular speed of about 55 000 μrad s−1. The driving resolution of the actuator was 0.34 μrad, and the maximum vertical loading capacity and torque were tested to be 6 kg and 30 N · mm, respectively. In addition, both clockwise and anticlockwise rotations were realized by simply changing the direction of the driving voltage waveform, and furthermore, under the same experimental conditions, very similar output performances were achieved in clockwise and anticlockwise rotations. Compared with some previously reported stick-slip piezoelectric rotary actuators, it was confirmed that the vertical loading capacity and driving resolution of the designed actuator here had been improved, which would be beneficial to its practical application.
