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.
Программа
- Week 1 - Week 1: Fundamentals of Fluid Power
This week: An overview of the course, introduction to hydraulics and pneumatics, and introduction to fundamental concepts of fluid power through the cylinder. - Week 2 - Week 2: Components and Concepts: Part 1
This week: circuit diagrams, the written language of fluid power, and how fluid flows through conduits. We hope that you find the hydraulic circuits on the mowing machine as interesting as we did. - Week 3 - 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... - Week 4 - 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 th... - Week 5 - 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 encou... - Week 6 - 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 ...

L'université du Minnesota, Twin Cities est une université américaine fondée en 1851.
Elle se situe conjointement dans les villes de Minneapolis et de Saint Paul dites les « villes jumelles (Twin Cities) » de l'État du Minnesota aux États-Unis. L'université constitue la partie la plus ancienne et plus grande du système universitaire du Minnesota. Elle est souvent classée parmi les 30 meilleures universités au monde par le classement de Shanghaï (Academic Ranking of World Universities).
Son corps étudiant est le deuxième plus grand des États-Unis avec 52 557 étudiants, et un rapport de 1 professeur pour 16 étudiants. Il est situé sur deux campus dans chacune des deux villes reliés par un système d'autobus réservé à l'université. À cause de la géographie particulière du Minnesota (plus de 12 000 lacs, et des centaines de kilomètres de parcs et de forêts), l'université a une activité de recherche intense en environnement, ressources et énergies renouvelables et développement durable. Son impact économique annuel est estimée à 8,9 milliards de dollars sur l'économie locale.
