Fluid Power Systems
Course Syllabus
Course Description
Analysis and design of fluid power systems used in agricultural, industrial and processing equipment. Selected topics to include: positive displacement components, control devices, actuators, fluid transmission and system dynamics. Lecture, two hours; laboratory, two hours per week. Prereq: ME 330, ME 340 and engineering standing or consent of the instructor. (3 credit hours)
Course Rationale
Manufacturers of agricultural, industrial, and processing equipment rely heavily on the application of hydraulics for distributing power and controlling machine function. While engineering courses in fluid mechanics and automated controls provide graduates with analytical skills, little is done to bridge the gap between theory and practical application. This course is designed to bridge gap by providing appropriate theory and illustrating its practical application to the design of fluid power and control circuits.
The course begins with a review of relevant fluid mechanics principles and proceed with treatments of individual components. Components to be analyzed include: pumps, actuators, lines, valves and other related components. Discussions of individual components will include: principles of operation, mathematical models, and design considerations. The remainder of the course is devoted to the analysis of various circuits, case studies of existing circuits, and design considerations for new circuits and applications.
Educational Outcomes
Students will be guided in the analysis and design of fluid power components and circuits. On completion students should be able to:
1. Understand principles of operation and design considerations for incorporating various components into fluid power circuits;
2. Develop mathematical models of individual hydraulic components to aid in the analysis, selection and optimization of hydraulic circuits;
3. Select and integrate commercially available components into fluid power circuits to facilitate power transmission and machine function control or agricultural, industrial and processing machinery; and
4. Apply standard practices used in the design of common circuits on both mobile and stationary hydraulic equipment.

Homework, Presentations, Exam and Grading
During the semester you will complete numerous homework and laboratory report assignments. Assignments may not be turned in after the due date (not counting excused absences). If an exception is made, they will be penalized 20% for each day late. Persons with excused absences (according to University policy) may in some cases be able to make up the material. In these cases, if it is not feasible to duplicate a missed assignment, the assignment will not be factored into the final grade. More explicit definitions of the course requirements are as follows:
Homework Assignments: You will be given several problem solving assignments to complete. Be sure you understand the specifics of the assignment and respond accordingly. Homework assignments will count for 25% of your final grade.
Laboratory Reports: Many of the laboratory investigations will require the development of formalized lab reports. These reports are to be prepared and submitted individually, even though some laboratories will be conducted in teams. At the option of the instructor, brief quizzes will be given in place of the lab report. Laboratory reports and quizzes will count for 25% of your final grade.
Midterm Exam: A scheduled midterm exam will be administered as indicated in the course outline. This exam will be comprehensive of the course materials, lecture and laboratory, covered to that point in the semester. The midterm exam grade will count for 25% of your final grade.
Final Exam: A comprehensive final exam will be administered at the end of the semester during the regularly scheduled exam period. You will be given example questions during the last two weeks of class. The final exam will count for 25% of your final grade.
Grading Schedule:
100% < A < 92%
92% < B < 83%
83% < C < 74%
74% < D < 65%
65% < E

plagiarism or cheating will not be tolerated. This behavior
will result in a final course grade of "E" and charges of academic misconduct!
