Piezoelectric ceramic stacks for underwater transducers
2015 IEEE Underwater Technology (UT), 2015An analytical model is presented of a stack of annular rings used in underwater Tonpilz and Flextensional transducers to radiate high acoustic power. The length of each ring is much less than the average diameter. The model is based on exact solutions to exact piezoelectric governing equations for rings. Boundary and continuity conditions are satisfied

Large signal measurements on piezoelectric stacks
Ferroelectrics, 1995The knowledge of the dielectric large signal properties of piezoelectric actuators for dynamic use is necessary to estimate the limits of application, to optimize the driving electronics, and to improve the actuator materials. A measurement technique has been developed for determination of the large signal parameters capacity, loss tangent, loss power,

High Performance ‘‘V-stack’’ Piezoelectric Actuator
Journal of Intelligent Material Systems and Structures, 2004A comparative analysis of the state-of-the-art actuators is conducted. A new piezoelectric actuator design is presented. It is compact, simple, sturdy, and leverages stroke geometrically with minimum force penalties. The ‘‘V-stack Piezoelectric Actuator’’ consists of a base, a lever, two piezoelectric stacks, and a pretensioning element.

Durability Properties of Piezoelectric Stack Actuator
Japanese Journal of Applied Physics, 1998Changes of temperature were measured for stack actuators having various values of E c and bending strength. The increase of temperature was 75°C in the center of low E c stack for a starting environment temperature of 120°C with 130 Hz driving frequency.

Compact piezoelectric stacked actuators for high power applications
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2000Small, hollow, multilayer actuators with a diameter of 3 mm were fabricated by the stacking method from piezoelectric hard lead zirconate titanate (PZT) ceramics. Langevin vibrators were also constructed with the hollow multilayer actuators. The performance capabilities of the actuator and Langevin vibrator samples were examined under high-power ...

Analysis on coupled vibration of piezoelectric ceramic stack with two piezoelectric ceramic elements
The Journal of the Acoustical Society of America, 2019A longitudinally polarized piezoelectric ceramic stack with two piezoelectric ceramic elements is an important part of sandwich piezoelectric transducers. The three-dimensional coupled vibration of piezoelectric ceramic stack is analyzed. Since the longitudinal and radial dimensions of particular piezoelectric ceramic stacks are approximately equal ...

Simulation model of the piezoelectric stack actuator
Proceedings of the 13th International Carpathian Control Conference (ICCC), 2012Piezoactuators become a perspective component for micromechanics and active vibration control. The piezoactuator as a microdrive operates on the principle of the reverse piezoelectric effect. Mechanical properties of the piezoactuators are as follows: high frequency range of operation, small travel range and large applied force.

Actuators using piezoelectric stacks and displacement enhancers
SPIE Proceedings, 2015Actuators are used to drive all active mechanisms including machines, robots, and manipulators to name a few. The actuators are responsible for moving, manipulating, displacing, pushing and executing any action that is needed by the mechanism. There are many types and principles of actuation that are responsible for these movements ranging from ...
