Book excerpt: Piezohydraulic actuation is the use of hydraulic fluid to rectify the high frequency, small stroke oscillation movement of the piezoceramic stack into a unidirectional movement. This paper presents a quasi-steady incompressible flow model and a compressible flow model for performance simulation. These two models are derived based on the energy equations for hydraulic flow in circular pipe. Major losses and minor losses are identified and incorporated in the model. Assumptions and approximations were made to minimize computation effort while achieving good accuracy. A piezohydraulic actuation system with active valves is then built and tested. Comparison with test results shows that the simulations accurately predict system performance under loads at which value leakage is not present. The results reveal that friction losses due to viscosity are a major limitation of performance for the current test setup when operating at higher frequencies.

Available in PDF, EPUB and Kindle. Book excerpt: The book serves as a unique integrated platform, which not only describes the design methodology of electro-hydraulic actuation systems but also provides insights into the design of the servo valve, which is the most important component in the system. It presents a step-by-step design process, comparative tables, illustrative figures, and detailed explanations. The book focuses on the design and testing of electro-hydraulic actuation systems, which are increasingly being used in motion control applications, particularly in those where precision actuation at high operational rates is of prime importance. It describes in detail the design philosophy of such high-performance systems, presenting a system used as a physical test setup together with experimental results to corroborate the calculations. Of particular interest are the electro-hydraulic servo valves that form the heart of these actuations. These valves are complex and not much data is available in open literature due to OEM propriety issues. In this context, the book discusses the elaborate mathematical models that have been derived and an approach to validate the mathematical models with test results. Presenting the complex methodology in simple language, it will prove to be a valuable resource for students, researchers, and professional engineers alike.

The piezohydraulic actuator utilizes a lead zirconate titanate (PZT) stack actuator and a hydraulic amplification design to achieve relatively large displacements required to control flow through a microjet with an orifice diameter of approximately 400 fým. Displacement amplification of 81 times the stack actuator displacement was achieved using a dual-diaphragm design to seal the fluid within a converging nozzle.

Book excerpt: Piezoelectric actuators are simple structures with compact sizes that provide quick and precise responses to an electrical stimulus. The response of the piezoelectric actuator can be a mechanical displacement or a blocking force with the magnitude determined by the structure's geometry and the electromechanical properties of the materials used. This book presents topical research in the study of piezoelectric actuators. Topics discussed include thick-film piezoelectric actuators prepared by screen-printing; pressure control of vehicle ABS using piezoactuator-based valve modulators; ultrasonic actuators based on the Langevin transducer; the dynamics of hinged-hinged beam using piezoelectric absorbers and modelling and control of piezoelectric actuator systems.
