“…Two common piezoelectric materials are widely used in many recent studies [31][32][33][34][35][36], which are piezo-ceramics, PZT (Lead Zirconium Titanate) and piezo-polymer, PVDF (Polyvinylidene Fluoride) [11,37,38]. Piezo-ceramic PZTs can be utilized both as sensor and actuator because they are applicable in the wide range of frequency and required lower actuating voltage; Piezo-polymer PVDFs are usually used as sensor [23,24].These materials may be analysed for the configuration in which the piezo-sensor and/or piezo-actuator is attached to a base structure and then the dynamic behavior of the total composite structure is modeled accordingly [24].…”

a b s t r a c tAn efficient analytical method for vibration analysis of a Euler-Bernoulli beam with Spring Loading at the Tip has been developed as a baseline for treating flexible beam attached to central-body space structure, followed by the development of MATLABÓ finite element method computational routine. Extension of this work is carried out for the generic problem of Active Vibration Suppression of a cantilevered Euler-Bernoulli beam with piezoelectric sensor and actuator attached as appropriate along the beam. Such generic example can be further extended for tackling light-weight structures in space applications, such as antennas, robot's arms and solar panels. For comparative study, three generic configurations of the combined beam and piezoelectric elements are solved. The equation of motion of the beam is expressed using Hamilton's principle, and the baseline problem is solved using Galerkin based finite element method. The robustness of the approach is assessed.

“…These elements are selected with different nature ranging from linear to higher order, triangular to quadrilateral, and improved to regular elements to provide wide range of variety to the present comparison. All these elements are tested using bench mark problems from the literature [19] , [20] for elastic and aero-elastic analyses with analytical results and/or experimental measurements. The element shape functions are derived using MATHEMATICA [21] software and then implemented into MATLAB [22] codes to solve the selected problems.…”

“…Xu et al (2007) adopted a genetic algorithm to optimize the number and placements of the actuators and control parameters of smart trusses. Ramesh Kumar and Narayanan (2007) and Safizadeh et al (2010) all used a genetic algorithm to find the best location of actuators for flat plate structures. The aforesaid optimization studies are mainly aimed at flat plate or truss structures.…”

The investigation focuses on simultaneously optimizing the locations and thicknesses of piezoelectric curved actuators as well as transient control voltages to achieve the best performance index. A curved shell element is deduced and the nodal displacement constraint equations are used to couple the piezoelectric curved shell element and the base shell element. Then the dynamic finite element equations of the piezoelectric shell structure are formulated. Based on the optimal vibration control theory, an integrated design optimization model is proposed. The linear quadratic performance index is taken as the objective function, and the control voltages as well as the number and volume of the actuators are considered as the constraints. The design variables include not only the locations and control voltages but also the thicknesses of the piezoelectric actuators. A two-layer optimization scheme is proposed to address this optimization problem with discrete and continuous variables coexisting. Because the control voltage is transient and time-varying, the linear quadratic optimal controller is used for the optimal control voltages in the inner layer. A simulated annealing algorithm is employed to optimize the locations and thicknesses of actuators in the outside layer. Numerical examples are implemented to demonstrate the accuracy of the curved shell element, the validity of the theoretical model, and the feasibility and effectiveness of the proposed optimization scheme.
