Overview
To provide basic knowledge and to develop specialistic competences in the field of experimental characterization of fluid power components for automotive applications.
At the end of the course, the student will be able to:
1. Build simplified architectures test-rigs;
2. Complete autonomously different sets of experimental qualifications;
3. Produce complete and explanatory test reports;
4. Discuss in clear and concise way the fundamental concepts of the course;
5. Explore autonomously some collateral aspect of interest
Admission requirements
Basic concepts in thermodynamics, fluid-dynamics, mechanics of machines, mechanical design, electrical engineering, automatic control, electronics and measurements systems
Course contents
The course will be held in the first semester of the course, and it consists of 60 teaching hours (6 CFU).
The contents below reported could be integrated (or partially modified) depending on students feed-back.
The division in CFU is purely indicative.
Introduction (4 CFU)
Hydraulic fundamentals and hydraulic fluids.
Fluid Power components (volumetric machines and control valves).
Performance characterization of the basic hydraulic system.
Hydrostatic Transmissions, DCT and Robotic Gear-Shifts
Teaching methods
The course lasts 6 CFU, 2 CFU dedicated to theory and 4 CFU dedicated to experiments and exercises. The course is based on face-to-face lectures, using multi-medial devices (note: based on the evolution of COVID-19 emergency, the course could be delivered via web-conferencing technology). The attendance is not mandatory, but it is strongly recommended. The course is lectured in Italian. All the information, together with the teaching material, will be available on the Moodle and/or Teams platforms. Working students not attending classes must contact the Teacher to receive specific guidance. Reception: by appointment assigned by e-mail
Assessment methods
The final exam consists in a test specifically addressed to capture the student ability in complete a simple experimental test. The final exam is developed "in presence", except for particular conditions imposed by security reasons. The final test normally lasts 1 hours (approximately), and the only device allowed is a not programmable scientific calculator. The final exam results are expressed in thirties, and the test correction is communicated though Esse3 platform within 10 working days. The Course development foresees a mid-term test during the mid-term suspension of the teaching activities. The mid-term test has the same characteristics of the final exam, but is referred to the arguments faced in classroom in the first part of the Course. The grade of the mid-term test is expressed in thirties, and the Student overcoming this test has the right to face up to a reduced final test (which include only the arguments faced during the teaching second period). In this case, the final grade is determined as the algebraic mean value between med-term and final reduced tests. Please refer to the Teacher for more details about mid-term test temporal validity.
Learning outcomes
The attendance of this course will allow the Student to:
1. gain a good knowledge in the field of the experimental analysis of fluid power components for automotive applications
2. learn how manage autonomously the basic instrumentation to build an efficient test-rig;
3. develop a good sensitivity about the influence of main design and operating parameter on components behavior;
4. develop good communication skills
