“…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 new approach in the development of aircraft and aerospace industry is geared toward increasing use of electric systems. An electromechanical (EM) piezoelectric-based system is one of the potential technologies that can produce a compactable system with a fast response and a high power density. However, piezoelectric materials generate a small strain, of around 0.1–0.2% of the original actuator length, limiting their potential in large-scale applications. This paper reviews the potential amplification mechanisms for piezoelectric-based systems targeting aerospace applications. The concepts, structural designs, and operation conditions of each method are summarized and compared. This review aims to provide a good understanding of piezoelectric-based systems toward selecting suitable designs for potential aerospace applications and an outlook for novel designs in the near future.

“…One of the significant shortcomings of inchworm type piezoelectric is the complex structure which brings trouble for the manufacture and control. Figure 8 shows the structure of the proposed simplified piezoelectric actuator based on the parasitic movement of the flexure mechanism by Li et al [26]. With the help of the parasitic movement of the flexure mechanism, only two piezoelectric elements are needed.…”
