“…However, the piezoelectric stack is not suitable for high-frequency excitation. Therefore, as shown in Figure 10(e), an FHMs-PSSA with the dual-mode excitation method was proposed, which excited the high-frequency vibration of the foot by ultrasonic excitation of the piezoelectric plate to suppress the backward motion (Ning et al, 2021). The backward motion was effectively suppressed in the above studies, but still existed.…”

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.

“…It has several advantages over standard rigid hinges, such as no return stroke, no friction, no gap, no noise, no wear, a small size, high motion sensitivity, and steady motion. [1][2][3][4] Therefore, flexure hinges are used in many devices, such as a mirror mount, 5,6 positioning-vibration isolation stage, 7 piezoelectric stick slip actuator, 8,9 micro-positioning stage, [10][11][12] and accelerometer. 13 Flexure hinges can be categorized as single-axis, double-axis, or multi-axis based on the number of rotational axes and the functions used.…”

To achieve the requirement of flexure hinges for specific optical precision equipment, a new triangular bi-axial flexure hinge is proposed. The analysis model for the flexibility of the triangular bi-axial flexure hinges is derived. After that, the linear and nonlinear finite element methods are used to verify the analysis model. Then, the physical dimensions of the hinge are optimized using the multi-island genetic algorithm in conjunction with the finite element method, and the rotational stiffness and center drift are diminished. Static analysis and modal analysis of the hinge are conducted. A test system was built to gage the flexure hinge’s rotational stiffness. The results demonstrated that there was good agreement between the analytically calculated value, simulated calculated value, and experimental value. To summarize, the analysis model met the design requirements of the triangular bi-axial flexible hinge, and the multi-island genetic algorithm effectively optimized the physical dimensions of the hinge and enhanced its performance. The design process provides new ideas for the design of other forms of hinges.

“…The driving tip was set on its top by cantilever flexible beam. The output force of their actuator was tested as 2.7 N. It should be stressed that the right-circle flexure hinge is frequently employed in the flexure hinge type piezoelectric stick-slip actuators (Li et al, 2020; Ning et al, 2021; Tang et al, 2020). However, the right-circle flexure hinge has relatively greater structural stress, which is validated in the existing works and they also indicate that the Z-shaped flexure hinge can effectively reduce structural stress and improve the working life (Li et al, 2017a, 2018).…”

A new piezoelectric stick-slip actuator using stair type flexure hinge is proposed and developed in this work. It’s spirited by referencing the reported “Z-shaped” flexure hinge in the literatures and the idea of asymmetric structure. In this design, the PZT stack can generate elongation displacement under the excitation of sawtooth signal, and then the elongation can be transmitted into the vertical and horizontal displacements on the driving tip by the stair type flexure hinge. The slider is pressed by the vertical displacement and driven by the horizontal displacement, respectively. The working principle of the proposed actuator is clarified. The statics characteristics are investigated by the theoretical and simulation methods. Finally, the mechanical output characteristics of the developed prototype are tested. The maximum output velocity is 8.5 mm/s when the voltage and frequency are 100 V and 720 Hz. The maximum output force is tested as 2.6 N when the preloading force is 3 N. The experiment results validate the feasibility of the proposed piezoelectric stick-slip actuator based on stair type flexure hinge.
