Abstract:
This article presents the actuating performance of a one-degree-of-freedom (DOF) positioning device using spring-mounted piezoelectric (PZT) actuators. To employ a spring with a preset compression, the operational range of a PZT actuator could be simply enlarged, and a sliding table actuated by PZT impact force might feature long stroke and high-precision positioning ability. An experimental set-up consisting of two spring-mounted PZT actuators was configured to examine the actuating characteristics. According to experimental results, a sliding table with a heavy mass of 172 g could be actuate

A two noded active sandwich beam element is formulated by employing layerwise Timoshenko’s beam theory. Displacement continuity conditions are imposed between different layers of the sandwich. This element is used to model an adaptive sandwich beam with macro-fiber composite (MFC) as extension actuator and shear actuated fiber composite (SAFC) as shear actuator. Influence of thickness and volume fraction of the active fiber (PZT-5A and single crystal PMN-PT) in the composite actuators on the actuation performance of the sandwich beam is investigated.

Abstract:
A novel piezoelectric micro-actuator with actuating range amplification structure has been proposed. This actuator is unique in that the leverage type amplification structure enables large actuating movement with low voltage. In case of general piezoelectric thin film actuator, applied voltage is low and almost zero power is consumed. Its switching time is very fast in comparison with electrostatic actuators and thermal actuators. However, the most drawback of piezoelectric actuator is short actuating range. A 100μm length PZT actuator can only make movement of 100. In this research, we sugges
