Composite Piezoelectric Assemblies for Torsional Actuators

A new piezoelectric actuator was developed for the direct production of large angular displacement and torque, with a monolithic, solid state device. The intended application of this device is to control vibration and noise in aircraft, helicopter, spacecraft and in manipulators and positioners wher...

Description
Summary:A new piezoelectric actuator was developed for the direct production of large angular displacement and torque, with a monolithic, solid state device. The intended application of this device is to control vibration and noise in aircraft, helicopter, spacecraft and in manipulators and positioners where direct rotary motion is required. Actuator design and assembly methods, materials preparation, poling procedures, and test results for joint strengths, and actuator output capabilities are discussed.
