Learning outcomes |
The student must acquire basic knowledge about the vibration phenomena occurring at components and engineering systems as to be able to analyze physical and mathematical models representative of different vibration problems. In parallel, a short introduction to the study of noise is undertaken aiming at understanding the physic principles of sound propagation and its implications in engineering systems.
