Design Methodology for engineers who use and apply proportional an servo valves to control electrohydraulic machines

Hardbound. The first point of reference for design engineers, hydraulic technicians, chief engineers, plant engineers, and anyone concerned with the selection, installation, operation or maintenance of hydraulics equipment. The hydraulic industry has seen many changes over recent years and numerous new techniques, components and methods have been introduced. The ninth edition of the Hydraulic Handbook incorporates all these developments to provide a crucial reference manual for practical and technical guidance.

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.

Today, the hydraulic or fluid power systems on a car, such as brakes and power steering, are strictly using fluid power. In the future, these systems may become totally electric, without any hydraulic or fluid power. Until then, the industry is using a combination of electronics and hydraulics, thus the name electrohydraulic. Through decades of research and experience, BOSCH has developed comprehensive knowledge in the field of electrohydraulics. Electrohydraulic Proportional and Control Systems conveys the state-of-the-art in electrohydraulics by presenting modern proportional control valves and servo solenoid valves, as well as open-loop and closed-loop control concepts. The operating principles of hydraulic and electronic components are described clearly and systematically in this book.Contents include: Proportional Control Valves Servo Solenoid Valves Servovalves Servo Cylinders Measurement Systems Proportional Technology Applications in Industrial Hydraulics Control Technology Applications in Industrial Hydraulics Proportional Control Valve Applications in Mobile Hydraulics Servo Solenoid Valve Applications in Mobile Hydraulics Field Bus Connection of Hydraulic Components Commissioning and Maintenance.
