This book was created because system dynamics courses in the standard mechanical engineering curriculum do not cover fluid power, even though fluid power is essential to mechanical engineering and students entering the work force are likely to encounter fluid power systems in their job. Most system dynamics textbooks have a chapter or part of a chapter on fluid power but typically the chapter is thin and does not cover practical fluid power as is used in industry today. For example, many textbooks confine their discussion of fluid power to liquid tank systems and never even mention hydraulic cylinders, the workhorse of today’s practical fluid power. The material is intended for use in an introductory system dynamics course that would teach analysis of mechanical translational, mechanical rotary and electrical system using differential equations, transfer functions and time and frequency response. The material should be introduced toward the end of the course after the other domains and most of the analysis methods have been covered. It replaces or supplements any coverage of fluid power in the course textbook. The instruction can pick and choose which sections will be covered in class or read by the student. At the University of Minnesota, the material is used in course ME 3281, System Dynamics and Control and in ME 4232, Fluid Power Control Lab.
