Vibrations of mechanical systems are a major cause of sound radiation in our environment. The course therefore offers students the possibility to become familiar with the physics of vibrations as a prerequisite to vibroacoutics, that is the study of sound radiated by vibrating structures.
Introduction to vibrations of mechanical systems, starting from the simple unidimensional oscillator to the multiple degree of freedom oscillations, before extended the lecture to the dynamics of continuous systems. This includes: • Basics of dynamic equation for discrete or continuous systems by energetic approach • Oscillation of a single degree of freedom oscillator, with or without damping, free or forced • Response to arbitrary excitations • Multiple degree of freedom oscillations • Vibrations of continuous system • Introduction to experimental modal analysis
