“…In the paper by Wang and Cross (1999) there is an issue of a three-layer converter extended and solved, whereas in (Xiang and Shi, 2008) -a multi-layer one. The static characteristics of two-layer converters with different length of layers are shown in (Park and Moon, 2005;Raeisifard et al, 2014;Mieczkowski, 2016).…”

This paper presents test results for deformation conditions of three-layer, piezoelectric cantilever converters subjected to various electrical and mechanical boundary conditions. A general solution has been developed based on implementation of piezoelectric triple segments (PTS) to the beam. A working mechanism and conditions for strain of the PTS segment have been determined. Basing on the general solution, for the cantilever actuator subjected to an external force (of single and dual PTS segments) and a uniform load (of single PTS segment), particular solutions have also been developed. Moreover, dimensionless frequencies of the oscillating motion for the analyzed converters have been determined. In the next step, the influence of such factors as length, quantity and position of PTS segments, their relative stiffness and unit weight on values of the obtained frequencies of vibration have been defined. The resulting analytical solutions have been compared with the developed FEM solution.

“…To define constitutive equations, the method (described in detail in papers [Mieczkowski, 2016;Mieczkowski, 2017]), which allows for implementation to a homogeneous beam two types of modules, hereinafter referred to as PBS (piezoelectric bimorph segment) and PTS (piezoelectric triple segment) was used. This allows for including in electromechanical characteristics of the segment a local change in stiffness and strain, which are caused by the transverse piezoelectric effect (Curie et al, 1880).…”

“…The averaging value of the moment of inertia JoT (16) -calculated in relation to the neutral layer -was determined in the same way as in the paper (Mieczkowski, 2016), using the method of transformation of the cross sectional area (Fertis, 1996).…”

“…Then Wang and Cross (1999) extended and solved the issue of a triple segment, while Xiang and Shi (2008) -a multilayer one. In papers (Park and Moon, 2005;Dunsch and Breguet, 2008; Rahmoune and Osmont, 2010;Raeisifard et al, 2014, Mieczkowski, 2016, Nguyen et al, 2018, results of piezoelectric bimorph testing were given, wherein their design featured piezoelectric layer of length other than that of a non-piezoelectric component. The paper (Mieczkowski, 2017) analysed static and dy-namic characteristics of a three-layer actuator, made of a nonpiezoelectric component and two piezoelectric layers of the same length and thickness.…”

The paper presents the analysis of electromechanical characteristics of piezoelectric converters subjected to an electric field and mechanical load. The analyses were performed based on a method consisting implementation of special segments responsible for electrical boundary conditions to a homogeneous beam. Constitutive equations were developed, allowing one to obtain static electromechanical characteristics for piezoelectric actuators with freely defined boundary conditions and geometry. Moreover, based on constitutive equations obtained, a particular solution for cantilever transducer subjected to concentrated force has been developed. The resulting analytical solution was compared with the data available in the literature, and the developed FEM solution. Furthermore, the influence of factors such as relative length, thickness and location of particular piezoelectric layers on electromechanical characteristics of the transducer was defined.
