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.
