Fluid power has the highest power density of all conventional power-transmission technologies. Learn the benefits and limitations of fluid power, how to analyze fluid power components and circuits, and how to design and simulate fluid power circuits for applications.
In this course, you will be introduced to the fundamental principles and analytical modeling of fluid power components, circuits, and systems.
You will learn the benefits and limitations of fluid power compared with other power transmission technologies; the operation, use, and symbols of common hydraulic components; how to formulate and analyze models of hydraulic components and circuits; and how to design and predict the performance of fluid power circuits.
This course is supported by the National Science Foundation Engineering Research Center for Compact and Efficient Fluid Power, and is endorsed by the National Fluid Power Association, the leading industry trade group in fluid power.

Week 3: Components and Concepts: Part 2
This will be a busy week diving into valves and pumps. We will discuss how basic valves function, how to use them in hydraulic circuits, and how to calculate pressure drop for a given flow rate, or vice versa. The videos will directly address the discussion on the forum about seeing hydraulic components working in real world circuits. In our discussion of pumps we will look at many different positive displacement pumps, exploring flow ripple and pump efficiency, look at the supporting components that form a hydraulic power supply, and see how we can make a transmission with a hydraulic pump and a motor. We are now into the heart of this course; we hope you enjoy seeing the components come together into useful circuits.

Week 4: Predicting Performance Through Simulation
This week is entirely devoted to you learning how to use Simscape Fluids (formerly SimHydraulics), the fluid power simulation application that we use in the course. The lecture provides an introduction to computer-based, object-oriented simulation, and goes through a demo of using Simscape Fluids. The homework assignment contains the real work because this is where you will learn to use Simscape Fluids. The homework ends with an open-ended problem that encourages you to branch out on your own and create and run simulations based on examples listed in the course Simscape Fluids resource page or on any other fluid power system that interests you. We will be monitoring the discussion boards to help you with any technical problems with Simscape Fluids.
*NOTE: The lecture videos were created using an earlier version of SimHydraulics; some small difference exist with the most recent version of Simscape Fluids, but the general approach is the same.
*THERE IS NO QUIZ THIS WEEK as we recognize that a few of you may not be able to get Simscape Fluids running on your computer. Happy simulating!

Week 5: Fluid Properties
This week we will take a dive into hydraulic fluids (no pun intended) and how their properties and behavior influence the circuit operation. In the lectures, you will see the water hammer effect and explore the assumption of fluid incompressibility. We encourage you to use your new knowledge of fluid behavior and simulation to create virtual experiments that explore how fluid properties influence the behavior of a circuit. Share your observations on the discussion forum.

Week 6: Advanced Components and Systems and Course Summary
This week you will learn about two new components, the accumulator, which stores hydraulic energy, and the servo valve, which provides fast and precise flow control. We will then be pulling together topics from throughout the course to look at servo hydraulic systems and hydraulic hybrid vehicles. You will get a chance to use simulation to explore how these advanced systems function and how the behavior of individual components influences the system operation.

Good course with basic review of Fluid mechanics in pipe flow, hydraulics component and application as well as basics in Simscape. More intensive version of this course would be great
Teachers were great and made the subject quite interesting. The accumulator portion will aid me in further understanding the operation of fluid equipment at work. Thanks for this!
