Hydraulic Power System Analysis

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.

Structured System Analysis

A New Technique

This book provides guidelines for the analysis of systems. It develops rules for hierarchical placement of subunits and shows how information flow affects the placement of subunits of a system. The determinants contributing to instability of a system are also discussed. The guidelines are developed and the structure of systems are investigated by first defining the terms to be used and then providing a number of theorems about the attributes of systems. The theorem proofs depend solely on the definitions and previously proved theorems. Up to this time, good system design was an art form difficult to communicate to the student and to the professional. The theorems developed in this book provide a more structured framework for the analysis of systems and can lead both the novice and the advanced practitioner through the intricacies of designing systems.

Rather than proceeding with this analysis, as its complexity will lead us to areas
of expertise way beyond the scope of this book, let's see what conclusions can be
drawn from the examples presented in both this chapter and the preceding ...
