Available in PDF, EPUB and Kindle. Book excerpt: In the design of hydraulic systems which include servo-valves it is usual to describe the valve characteristics using steady-state considerations. Demands of increased precision and speed of response placed on these systems in recent times have necessitated further investigation into the dynamic response of electro-hydraulic servo-valves.A survey of research carried out on servo-valve characteristics and the transducers available for measuring pulsating flow is presented in Chapter A new, indirect method for measuring the oscillating flow-rate froma servo-valve is described in Chapter 2. The theory of the technique and the assumptions used are discussed.Verification of the usefulness of the technique was obtained with an analogue model. Accurate prediction of the flow-rate from a valve model with both steady-state and frequency dependent characteristics was obtained as detailed in Chapters 3 and 4«An experimental apparatus is described in Chapter 5 for implementing the indirect method. Measurement of the component characteristics and parameters and the calibration and measurement of the dynamic responses of the transducers are described.Three models for a servo-valve are discussed in Chapter 6 and used in simulations of the experimental system. One model uses the measured steady-state valve characteristic whilst the other models are based upon the analyses of other researchers which are extended for application to the experimental system.In Chapter 7 the responses of the models and the experimental system are compared. It is found that the three models agree closely. Frequency responses of the experimental system and the steady-state model arepresented and a possible explanation for their difference is described. Frequency compensation is shown to greatly extend the useful bandwidth of the steady-state model for system design and stability considerations.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Recommended Practice (ARP) provides definitions and background information for understanding the physical performance, and test procedures of electrohydraulic flow control servovalves.The recommendations are confined to interface definition and input/output characteristics. This ARP does not restrict or attempt to define the internal characteristics of servovalves. As such, the recommendations are equally applicable to valves having different internal functioning, different ratings, different physical size, and valves used with different fluids. In certain instances, standards for valve design are recommended for the purpose of interchangeability, as for example, valve polarity, mounting bolt and fluid port locations.The ARP provides extensive guidance for the preparation of Procurement Specifications and for functional testing. A sample Procurement Specification is provided in Appendix A. The primary focus of this ARP is on four-way valves. Three-way valves are discussed to a limited extent and terminology for pressure control valves is presented in Appendix B.This ARP is applicable to fluid power systems in all types of flight vehicles, and it is applicable to Military, Civil and Space design/certification standards. Additional specifications or specialized test procedures may be necessary to define special requirements for specific control systems, and such considerations are beyond the scope of this ARP. This revision of SAE ARP490 document is a result of a scheduled periodic document review. It incorporates changes recommended by the SAE A-6 Panel and committee members.
