Objectives

Fluid Power Systems for drive, transmission and control through fluid energy: Hydraulics and Pneumatics.
On conclusion of this course the student should be able to understand the technologies of Hydraulic and Pneumatic systems, the functional properties, sizing and selection of parts for an application.

Learning outcomes and competences

On conclusion of this course the student should be able to:
-understand the technologies of Hydraulic and Pneumatic systems,
-sizing systems
-understand the functional properties,
-be able to select components for an application
- be able to design hydraulic and pneumatic systems, following a specification

Working method

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Electricity

Instrumentation for measurement

fluid mechanics

mechanics: kinematics

Program

Graphical representation
Auxiliary components: filters and filtering, cooling, instrumentation.
Hydraulic circuit analysis, sizing and design.
System and component experimental testing

Mandatory literature

Teaching methods and learning activities

The course involves:
a)formal lecture classes, including tutorials for circuit analysis, sizing and design (TP)
b)extensive laboratory support sessions (PL)

Classes are fully supported by multimedia aids.
For each laboratory class there are milestones to be reached

Eligibility for exams

In order to obtain valid frequency the student must attend classes within the legal limits of frequency (>25%)

Calculation formula of final grade

Final mark for this course are based on:
A) Distributed evaluation, which totals a maximum of 55% of final marking, resulting from:
A1) random "mini tests"(of short duration) at formal lecture classes - 10% of final marking
A2) work group results during laboratory sessions - 10% of final marking
A3) special mid-term laboratory session individual evaluation - 15% of final marking
A4) end-of-term laboratory session individual evaluation - 20% of final marking

B) Final written exam, which totals a maximum of 45% of final marking

Remark: students are only approved in the course if computed final mark is above 9,5 units out of 20, subject to none of the partial evaluation (distributed and final exam) are not evaluated below 8,5 units

Examinations or Special Assignments

As described above

Special assessment (TE, DA, ...)

Working students may apply for a special evaluation procedure, based on:
A) one individual oral and written examination, in laboratory environment, with maximum value of 50% of final marking
B) one individual written exam, with maximum value of 50% of final marking

Classification improvement

A special evaluation improvement session may be possible for students.
A special oral and written individual examination may be undertaken to upgrade the distributed evaluation marking, and
A special written examination may be undertaken to upgrade the marking attributed to the final written exam.
