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 کاملNonlinear Vibration Analysis of Piezoelectric Functionally Graded Porous Timoshenko Beams
In this paper, nonlinear vibration analysis of functionally graded piezoelectric (FGP) beam with porosities material is investigated based on the Timoshenko beam theory. Material properties of FG porous beam are described according to the rule of mixture which modified to approximate material properties with porosity phases. The Ritz method is used to obtain the governing equation which is then...
