“…Aircraft engine rotor vibrations and bearing forces can be reduced using piezoelectric actuators (Leboi et al, 2010). Vibrations in the wings (Munteanu and Ursu, 2008) and the vertical stabilizer (Chen et al, 2013b; Gao et al, 2013) can be reduced dramatically using piezoelectric actuators as active dampers. An active buffet alleviation system has been tested on a 1/16th-scale model of a vertical stabilizer in a wind tunnel (Hanagud et al, 2002).…”

A traditional aircraft is optimized for only one or two flight conditions, not for the entire flight envelope. In contrast, the wings of a bird can be reshaped to provide optimal performance at all flight conditions. Any change in an aircraft’s configuration, in particular the wings, affects the aerodynamic performance, and optimal configurations can be obtained for each flight condition. Morphing technologies offer aerodynamic benefits for an aircraft over a wide range of flight conditions. The advantages of a morphing aircraft are based on an assumption that the additional weight of the morphing components is acceptable. Traditional mechanical and hydraulic systems are not considered good choices for morphing aircraft. “Smart” materials and structures have the advantages of high energy density, ease of control, variable stiffness, and the ability to tolerate large amounts of strain. These characteristics offer researchers and designers new possibilities for designing morphing aircraft. In this article, recent developments in the application of smart materials and structures to morphing aircraft are reviewed. Specifically, four categories of applications are discussed: actuators, sensors, controllers, and structures.

“…As a result, the MFC is equivalent to the external actuating force to be exerted onto the structure, which is a simpler and more reasonable method. Gao et al [12] arranged MFCs on vertical fin structures to deduce the MFC equivalent actuating bending moment equation and the sensing voltage equation by utilizing the classical plate theory (CPT), and accomplished the simulation and experiment of vibrational control of vertical fin structures based on negative feedback by establishing a simplified model of the vertical fin structures attached to the MFC with ABAQUS finite element software, proving that MFCs have a great controlling effect on the vertical fin structures. Li et al [13] studied the equivalent actuating force based on the elastic deformation theory under the condition of partial abhesion of the MFC, analyzed the influence of the percentage and location of delamination on actuating performance, and verified the experimental result.…”

A new piezoelectric composite, macro fiber composite (MFC) is recombined with piezoceramic fibers, an epoxy resin basal body, and an interdigitated electrode. It has been widely applied in vibration reduction and deformation control of thin-walled structures, due to its great deformability and flexibility. Research on its actuation performance is mostly concentrated on the MFC actuating force calculation based on classical plate theory (CPT), and the overall modeling of MFC and its structure. However, they have some deficiencies in the tedious calculating process and neglect of shear deformation, respectively. To obtain a precise MFC actuating force, the sinusoidal shear deformation theory (SSDT) is adopted to deduce the MFC actuating force formula, and global–local displacement distribution functions are introduced to help the MFC laminated plate structure satisfy the deformation compatibility and stress balance. For instance, in the end displacement calculation of the MFC laminated beam structure. The experimental result of the MFC laminated beam is compared with those of the MFC actuating force based on SSDT and on CPT, which indicates that the MFC actuating force formula based on SSDT can reach higher computational accuracy.

“…Piezoelectric transducers, with a unique piezoelectric effect that can convert electrical energy into mechanical energy and vice versa, have been actively investigated to achieve various application purposes, for instance, active vibration control (Abdeljaber et al, 2016; Gao et al, 2013; Sethi and Song, 2005; Sohn et al, 2009), vibration energy harvesting (Anton and Sodano, 2007; Erturk and Inman, 2011; Ewere and Wang, 2014; Harne and Wang, 2013; Tang et al, 2010, 2014; Wang et al, 2015b; Zhang et al, 2016, 2017), structural health monitoring (Habib et al, 2013; Kong et al, 2017; Park et al, 2003; Song et al, 2008; Zou et al, 2015), voltage transforming (Chen et al, 2009; Yang, 2007), and sound waves emitting and receiving (Asadnia et al, 2013; Liu et al, 2010; Martins et al, 2012).

An exact analytical model of multilayer piezoelectric-elastic spherical transducers is established in this article, and their dynamic characteristics are studied. Based on the linear theory of piezoelasticity, the dynamic analytical solution is derived in terms of Bessel functions, Lommel functions, Gamma functions, and Generalized Hypergeometric functions, and the electric impedance is obtained to determine the resonance frequencies. By proper selection of the layer number and geometric dimensions, the proposed model can approximately degrade into some special cases in the previous works, including single-layer piezoelectric spherical transducer, two-layer piezoelectric-elastic spherical transducer, and three-layer sandwiched piezoelectric-elastic-piezoelectric spherical transducer. Comparisons between the results of the proposed model and the ones of these special cases are also given and good agreements are found. Furthermore, parametric studies are conducted to discuss the effects of the key parameters on the dynamic characteristics of these special cases and a multilayer case, such as the first resonance and anti-resonance frequencies as well as the corresponding electromechanical coupling factor. This work contributes to an overall understanding of the dynamic characteristics of miniature piezoelectric hollow sphere transducers (BBs) and stacked piezoelectric spherical transducers. The developed model can be used to guide the design of the multilayer piezoelectric-elastic spherical transducers for promising applications in underwater acoustic detection, ultrasonic imaging, hydrophones, and nondestructive testing.
