Simulation by Bondgraphs: Introduction to a Graphical Method [Paperback]

Bondgraphs are a powerful tool in the simulation of mechanical, hydraulic, electric and thermal systems. They are used to represent engineering systems in written form by means of letter elements and their interconnections, called bonds, instead of in the form of numerous equations. They may be used to increase the efficiency of new product design. This book introduces the reader to bondgraphs and their use on PCs. A broad variety of applications of this method in the simulation of the above systems is presented. Twenty fully worked examples complement the presentation.1 Simulation and Graphical System Models.- 1.1 Setting the Stage.- 1.2 Networks for Engineering.- 1.3 Mixed Introductory Topics.- 2 Bondgraphs as Networks for Power and Signal Exchange.- 2.1 Word Bondgraphs and Main Bondgraph Variables.- 2.2 Bondgraph Standard Elements.- 2.3 Computation Marks, Power and Causality.- 2.4 Simulation from Blockdiagrams and Bondgraphs.- 2.5 Nonlinearities and Block-Bondgraphs.- 2.6 Multiport Bondgraph Elements.- 2.7 Junction Structures and Transformations.- 3 Simulation and Design of Mechanical Engineering Systems.- 3.1 Opening of the Application Chapters.- 3.2 Mechanical Systems with Ground Reference.- 3.3 Systematic Writing of Mechanical Bondgraphs with Moving Reference Points.- 3.4 Slip, Clutches and Electric Induction Motors.- 3.5 Transmissions and Efficiencies.- 4 Simulation of Fluid Power Systems and Hydrostatic Drives.- 4.1 Hydrostatic Power in Fluid Flow.- 4.2 Valve Controlled Actuators and Servomotors.- 4.3 Circuits and Hydrostatic Transmissions.- 4.4 Special Components and Devices.- 5 Electrical Circuits, Drives and Components.- 5.1 Electric Circuits and Components.- 5.2 Electric Motors.- 5.3 Capacitors, Inductors, Actuators and Real Transformers.- 6 Computational Overview, Practical Procedures and Problems.- 6.1 Programs for Simulation from a Bondgraph.- 6.2 Linear Control Theory, Eigenvalues and Calculating Step.- 6.3 Stability Preview and Steady State Bondgrapló!
