Connaissances
At the end of the course, the student will be able to explain:
- The concept of vibration mode, and associated modal parameters (modal mass, damping, stiffness notably)
- The concepts of resonance and anti-resonance
- The concepts of free response, impulse response, harmonic response, and frequency response function (FRF)
- The beat phenomenon
- The principle of orthogonality of mode shapes
- The principles of Lagrangian dynamics and Lagrange equations
-The principles of experimental modal analysis
Aptitudes
At the end of the course, the student will be able to:
- Model various mechanical systems as equivalent mass-spring systems, and hence infer properties such as resonance frequencies
- Obtain the equations of motion of various mechanical systems based on Lagrange equations, and hence infer resonance frequencies
- Conduct an experimental modal analysis on a mechanic system, or at least, be able to explain how to conduct such an experiment
- Propose strategies in vue of vibration alleviation
Compétences
At the end of the course, the student will be able to:
- Write a simple code (typically on Matlab) in view of numerically computing the dynamic response of a N DOF system
1) Introduction: importance of modal analysis and theory of vibrations in mechanical engineering applications
2) Single Degree of Freedom (DOF) systems : study of mass-spring systems, and equivalent modelling of mechanical systems as mass-spring systems
3) Multiple DOF systems : study of the dynamic behavior of N DOF systems
4) Lagrangian dynamics : basic principles of Lagrangian dynamics, and Lagrange equations
5) Vibration alleviation : introduction to Tuned Mass Dampers (TMD) and Dynamic Vibration Absorbers (DVA)
6) Introduction to rotor dynamics (if time allows)
If time and sanitary situation permits, one session in laboratory is planned, meant as an introduction to experimental modal analysis
