Organisation and examination

Teaching in the first semester, review in January

Schedule

Schedule online

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

The course provides the fundamentals of the dynamics of mechanical systems.
Course ouline

  • Review of Lagrangian and Newtonian dynamics and application to simple mechanical systems.
  • Single and multiple degrees-of-freedom systems: fundamentals(resonance frequency and mode-shape), response prediction to forced excitations.
  • Continuous systems and discretisation methods.
  • Dynamic behavior of rotating machines: critical speeds, balancing methods.
The theoretical concepts will be illustrated through hands-on exercices and vibration experiments performed in the classroom. One project will be assigned during the course semester.

Learning outcomes of the learning unit

The objective is to give to the students a solid background in the modelling and the simulation of the dynamical behavior of mechanical structures. Typical vibration problems encountered in mechanical systems and rotating machines will illustrate the theory.

Prerequisite knowledge and skills

This course requires basic knowledge of fundamental calculus, differential equations and applied mechanics.

Planned learning activities and teaching methods

The course will also propose:


  • practice exercises;
  • experiments performed in the classroom;
  • homeworks.

Assessment methods and criteria

The final grade is based on the written examinations and on the homework reports. No document is allowed during the examinations.
A. Written examination of theory (45%) The theory examination consists in:


  • answering to one question of theory drawn in the list available on the students' portal myULiège;
  • giving some brief definitions and/or answering to a multiple-choice questionnaire.
B. Practical written examination (40%) The practical written examination consists in solving exercices similar to those given during the semester.
C. Homeworks (15%)
Written reports on the proposed homeworks are mandatory. The note of the homeworks is taken into account for the second session but is not reported in case of final failure.
 
There is no partial exemption for the examinations.

Adaptation of teaching commitments following the COVID-19 pandemic for the Aug-Sept 2020 session

Assessment subjects

The assessment subjects are the same as for the first session.

Assessment methods

The assessment will be based on a written examination of theory and on a written examination of exercises which will be organised as remote reviews in an open-book format through e-Campus.
1. Written examination of theory (45%)
The examination of theory will consist in answering to multiple response or multiple choice questions and open questions similar to the Wooclap sessions organized during the lectures. The questionnaire will be available at the date and time scheduled in the exam timetable. Students will have a limited time to answer the questions.
2. Examination of exercises (40%)
The practical written examination consists in solving exercises similar to those given during the semester. It will consist to write down the answers and to send a scanned copy through e-Campus in a limited time.
3. Homeworks (15%)
The notes of the homeworks realized during the first quadrimester will be taken into account for the second session.
