Organisation and examination
Teaching in the first semester, review in January
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.
- 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.
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:
- several practice exercises;
- experiments performed in the classroom;
- a homework.
Mode of delivery (face-to-face ; distance-learning)
Recommended or required readings

Edited by the Centrale des Cours de l'AEES
Assessment methods and criteria
The final grade is based on the written examinations and on the homework report. No document is allowed during the examinations.
A. Written examination of theory (50%) The theory examination consists in:
- answering to one question of theory drawn in the list available on the students' portal myULg;
- giving some brief definitions and/or answering to a multiple-choice questionnaire.
C. Homeworks (10%)
A written report on the proposed homework is mandatory. The note of the homework 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.
