Meso scale flextensional piezoelectric actuators
We present an ultra-thin meso scale piezoelectric actuator consisting of a piezoceramic beam and a carbon fiber displacement-amplification frame. We show that the actuator can be designed to achieve a wide range of force/displacement characteristics on the mN/μm scales. The best performing design achieved a free displacement of 106 μm and a blocked force of 73 mN, yielding a total energy densit...
متن کاملOptimum Design of Flextensional Piezoelectric Actuators into Two Spatial Dimensions
In control of distributed parameter systems the piezoelectric actuators are of common use. The topology optimization of a multiphysic model in piezoelectricity is considered. The topological derivative of a tracking-type shape functional is derived in its closed form for the purpose of shape optimization of piezoelectric actuators. The optimum design procedure is applied to a micromechanism whi...
متن کاملOptimal shape and location of piezoelectric materials for topology optimization of flextensional actuators
Piezoelectric actuator has been increasingly used in MEMS system due to its advantage of generality and flexibility. A flextensional actuator consist of a piezoceramic device, which can convert electrical energy into mechanical energy and vice versa, and a flexible mechanical structure, which can convert and amplify the output piezoceramic displacement in the desired direction and magnitude. A ...
متن کاملMechanical Buckling of FG Saturated Porous Rectangular Plate with Piezoelectric Actuators
In this study buckling analysis of solid rectangular plate made of porous material bounded with the layers of piezoelectric actuators in undrained condition is investigated. Porous material properties vary through the thickness of plate with a specific function. Distributing of the pores through the plate thickness is assumed to be the nonlinear nonsymmetric distribution. The ...
متن کاملVibration Control of a Mechanical Structure with Piezoelectric Actuators - a Comparison of Bimorph and Stack Actuators
The practical results of the vibration suppression of a cantilever beam with a low voltage piezoelectric bimorph patch and a stack actuator are discussed. After the equation of motion of the controlled system is obtained by the finite element method, a modal analysis is performed to reduce the numbers of degrees of freedom. A modal linear quadratic feedback controller is realized on a real-time...
