A hydraulic system controls the transmission of energy. It transforms the mechanical energy of a prime motor into fluid energy. It controls the fluid configuration and transforms the fluid energy into mechanical work at specified locations. Hydraulic systems feature high power density, sensitive response and precision of control, especially when operating under computer control. Thus, they have been widely used as the energy transmission control systems in aircraft, ships, construction machinery, machine tools and others. Therefore, it is indispensable for a mechanical engineer to become versed with hydraulic control technology. The technology is mainly associated with fluid mechanics and control theories, but it is related to the wider field of engineering as well. This book provides a comprehensive treatment of the analysis and design of hydraulic control systems which will be invaluable for practising engineers, as well as undergraduate and graduate students specializing in mechanical engineering. Firstly, the fundamental concepts of hydraulic control systems are addressed, and illustrated by reference to applications in the field of aviation engineering. Secondly, the fluid mechanics necessary for the comprehension of hydraulic elements are provided. The technology of the hydraulic components composing hydraulic control systems is addressed, the key focus being on how to apply theoretical concepts into the design and analysis of hydraulic components and systems. Finally, there is a discussion on fundamental control technology and its application to hydraulic servo systems. This includes the formation of hydraulic servo systems, basic control theorems, methods identifying the dynamic characteristics of hydraulic actuator systems, and a design method for hydraulic control systems. Numerical exercises are provided at the end of each chapter. Request Inspection Copy

Engineers not only need to understand the basics of how fluid power components work, but they must also be able to design these components into systems and analyze or model fluid power systems and circuits. There has long been a need for a comprehensive text on fluid power systems, written from an engineering perspective, which is suitable for an undergraduate-level course in fluid power. Fluid Power Circuits and Controls: Fundamentals and Applications encourages students to think of the collection of components as a system. The author illustrates each concept with a circuit diagram, and as each component is discussed, immediately places it in a circuit and analyzes its performance. This approach allows students to immediately apply what they have learned and encourages them to think about how the component operating characteristics interact with the rest of the circuit. Covering all aspects of the industry, this book: Develops the basic concept for power delivery with fluids Reviews basic concepts of fluid mechanics and discusses the key properties of the fluids Discusses the creation and control of flow and the various methods used to control pressure in a circuit Provides a detailed example of the classic problem of hydrostatic transmission design Presents characteristics of auxiliary components and applicable SAE standards Addresses pneumatics, focusing on the difference in power transmission for liquid and gas Discusses servo valves and proportional valves without requiring a background in automatic controls The text is richly illustrated, filled with fully worked example problems, and reinforced with exercises in each chapter. Fluid Power Circuits and Controls offers valuable design experience and the background its readers need to approach real-world fluid power problems with confidence.

This exciting reference text is concerned with fluid power control. It is an ideal reference for the practising engineer and a textbook for advanced courses in fluid power control. In applications in which large forces and/or torques are required, often with a fast response time, oil-hydraulic control systems are essential. They excel in environmentally difficult applications because the drive part can be designed with no electrical components and they almost always have a more competitive power/weight ratio compared to electrically actuated systems. Fluid power systems have the capability to control several parameters, such as pressure, speed, position, and so on, to a high degree of accuracy at high power levels. In practice there are many exciting challenges facing the fluid power engineer, who now must preferably have a broad skill set.

The excitement and the glitz of mechatronics has shifted the engineering community’s attention away from fluid power systems in recent years. However, fluid power still remains advantageous in many applications compared to electrical or mechanical power transmission methods. Designers are left with few practical resources to help in the design and analysis of fluid power systems, especially when approaching fluid power for the first time. Helping you overcome these hurdles, Hydraulic Power System Analysis demonstrates modern computer-aided analytical techniques used to model nonlinear, dynamic fluid power systems. Following an overview of fluid power, the authors examine various relevant fluid properties, energy calculations, and steady state and dynamic analysis along with a review of automatic control theory. Turning to modeling, the next few chapters address valves and motors and then apply dynamic modeling to examples relating to pumps, hydrostatic transmissions, and valves. The book includes a unique chapter showing how to combine flow resistance equations with the differential equations governing dynamic system performance. The final chapter translates electrical circuit theory concepts to noise attenuation in fluid power systems. Illustrated with many equations, practical computer modeling examples, and exercises, Hydraulic Power System Analysis provides a much-needed modernization of dynamic modeling for fluid power systems using powerful computational tools.
