Resolution composite shell with a layer of piezoelectric vibration analysis
In this paper, the vibration of composite cylindrical shell with piezoelectric layers in the interior and exterior surfaces is investigated. The composite shell without piezoelectric layers can be studied and compared the results with the results of other researchers, the cylindrical shell laminated with layers of piezoelectric vibration checked. The result is a three-dimensional elasticity equ...
متن کاملCeramic–Ceramic Actuator Composed of Two Piezoelectric Layers with Opposite Poling Directions
A ceramic–ceramic actuator composed of two piezoelectric ceramic layers with opposite poling directions was developed. One layer of the actuator had a high coercive electric field (PZT (Pb(Zr,Ti)O3)-I; Ec5 1.1 kV/mm), while the other had a relatively low coercive electric field (PZT-II; Ec5 0.6 kV/mm). The actuator was fabricated by cofiring a green compact composed of the PZT-I powder on top o...
متن کاملPiezoelectric-based Vibration Control in Composite Structures
This paper relates to vibration control using passive electrical shunt circuits. However, the vibration shunt control efficiency relies on the optimization of the vibration energy transfer between a structure and a Lead-Zirconate-Titanate (PZT) piezoelectric ceramic material. The problem is further complicated by the material composition of the substrate or host material the PZT is coupled to. ...
متن کاملRecent Progress on BaTiO3-Based Piezoelectric Ceramics for Actuator Applications
Due to issues with Pb toxicity, there is an urgent need for high performance Pb-free alternatives to Pb-based piezoelectric ceramics. Although pure BaTiO3 material exhibits fairly low piezoelectric coefficients, further designing of such a material system greatly enhances the piezoelectric response by means of domain engineering, defects engineering, as well as phase boundary engineering. Espec...
متن کاملNumerical and Experimental Characterization of Fiber-Reinforced Thermoplastic Composite Structures with Embedded Piezoelectric Sensor-Actuator Arrays for Ultrasonic Applications "2279
The paper presents preliminary numerical and experimental studies of active textile-reinforced thermoplastic composites with embedded sensor-actuator arrays. The goal of the investigations was the assessment of directional sound wave generation capability using embedded sensor-actuator arrays and developed a wave excitation procedure for ultrasound measurement tasks. The feasibility of the prop...
