Objectives of Programme's Learning Outcomes

• Mobilise a structured set of scientific knowledge and skills and specialised techniques in order to carry out mechanical engineering missions, using their expertise and adaptability.
• Master and appropriately mobilise knowledge, models, methods and techniques specific to mechanical engineering.
• Assess the validity of models and results in view of the state of science and characteristics of the problem.
• Contribute by researching the innovative solution of a problem in engineering sciences.
• Design and implement investigations based on analytical, numerical and experimental approaches.
• Adequately interpret results taking into account the reference framework within which the research was developed.

Learning Outcomes of UE

Get acquainted with the fundamentals of Acoustics. To understand the phenomena related to generation, propagation and perception of noise.
To address and solve acoustic problems likely to appear in industry with a particular concern on a rigorous analysis and a rigorous application of the theory. Sound measurement devices. At the end of the instruction, the students will be able to understand the exploitation of experimental vibrations (signals measurement, data-acquisition, industrial hardware and software, signal processing) in frequency and time domains; to get a basic knowledge of experimental modal analysis: practice, multi-channel survey, principle of some typical methods, limitations, validation; to propose efficient solutions in order to limit the structural vibrations (vibrations absorber, isolation, balancing technique, structural updating); to reflect critically on the practice of problems and solutions in vibration field.

Content of UE

The learning outcomes I-MRDV-007 is based on two parts. The first part is dedicated to a lecture course with specific theoretical issues (State-of-art in vibration data acquisition: signal processing: vibration classification, vibration sensors, signal processing; vibration analysis and post-processing: modal analysis theory and practice; anti-vibration solutions: applications of modal analysis, isolation, dynamic absorbers). The second part is based on a personal work using the outcomes. The learning outcomes I-MRDV-008 focuses Fundamentals of Acoustics: wave equation, pressure, particle velocity, sound celerity, acoustic impedance, acoustic intensity and power. Human perception of sound. Propagation of sound. Measurement. Experimental Acoustics. Principal laws and standards in Europe, Belgium and Walloon Region. Iso Standards. Audition loss of company workers.
Noise of machines: "emitter-propagation-receptor" model.

Type of Assessment for UE in Q2

• Presentation and works
• Oral Examination

Q2 UE Assessment Comments

For the learning outcomes I-MRDV-007, the main assessment is based on the laboratory reports (20% of the mark) and an oral examination (80% of the mark). During the oral examination (maximal duration: 4 hours), the students are allowed to consult (without writing) their notes during 10 minutes after having received the question. They then answer in a synthetic way on a sheet of paper from which they orally expose their answer. The secondary assessment is based on a presentation of the personnal work. For the learning outcomes I-MRDV-008, the oral exam consists of about 50% on theory and 50% on applications. For theory, the students may read their course notes during 10 minutes (but without writing anything). When the theoretical part is finished, students may have their notes for the exercizes.

Type of Assessment for UE in Q3

• Presentation and works
• Oral examination
• Written examination

Q3 UE Assessment Comments

For the learning outcomes I-MRDV-007, the main assessment is based on the laboratory reports (20% of the mark) and an oral examination (80% of the mark). Same as 1st session. The mark for the laboratory reports is automatically carried over, unless the student refuses it, in which case the oral examination is affected 100% of the mark. For the learning outcomes I-MRDV-008, the oral exam consists of about 50% on theory and 50% on applications. For theory, the students may read their course notes during 10 minutes (but without writing anything). When the theoretical part is finished, students may have their notes for the exercizes.
