Fluid Power System Dynamics
This minibook 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.

INTRODUCTION TO FLUID POWER, Fluid power is a term which was created to
include the generation, control, and application
of smooth, effective power of pumped or
compressed fluids (either liquids or gases) when
this power is used to provide force and motion
to mechanisms. This force and motion maybe in
the form of pushing, pulling, rotating, regulating,
or driving. Fluid power includes hydraulics, which
involves liquids, and pneumatics, which involves
gases. Liquids and gases are similar in many
respects. The differences are pointed out in the
appropriate areas of this manual.

timesFluid Power Basics
The term fluid power refers to energy that is transmitted via a fluid under pressure. With hydraulics, that fluid is a liquid such as oil or water. With pneumatics, the fluid is typically compressed air or inert gas. Fluid power’s motive force comes from the principle that pressure applied to a confined fluid is transferred uniformly and undiminished to every portion of the fluid and to the walls of the container that holds the fluid. A surface such as a cylinder piston will move if the difference in force across the piston is larger than the total load plus frictional forces. The resulting net force can then accelerate the load proportionately to the ratio of the force divided by the mass.
