Performance Modeling and Efficiency Analysis for a Piezohydraulic Pump with Active Valves
Piezoelectric actuation is an expanding field that makes use of piezoelectric materials that have high power density as actuators. These actuation systems have the potential higher power density than the traditional servo motor technology. However, due to tiny strain of the piezoelectric materials, …

Development and Analysis of the Lumped Parameter Model of a Piezo-Hydraulic Actuator
Hybrid actuation is an expanding field in which several systems, such as a mechanical, electrical, hydraulic, pneumatic, and/or thermal, among others, are integrated in order to combine certain aspects of each system, and achieve a better and more efficient performance under certain operating …

Piezohydraulic Actuator Design and Modeling Using a Lumped-Parameter Approach
The concept of piezohydraulic actuation is to transfer the reciprocal small stroke displacement of piezoceramics into unidirectional motion by frequency rectification through a hydraulic fluid. It takes advantage of the high force capabilities that piezoelectric materials have and couples it with …
