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.

Really excellent course for someone who wants to start learning the basics of fluid to advance level of hydraulic system where you can get a practical overview of the product been used in real life.
par AG30 mai 2020
This was the Best Course I have done so far. The instructors are totally dedicated to teach. They have given practical examples on field and industry for the Better Understanding.Thank You.
par SS24 sept. 2017
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
par JB15 sept. 2017
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!
