The aim of the course is to present the most important methodologies applied to predict the dynamic and oscillatory behavior of mechanical systems with linear characteristics.
Vibrations of single-degree-of-freedom linear systems, mathematical models, equations of motion, free and forced vibrations, response to different excitations (impulse, pulse, harmonic, periodic, non-periodic, general), Fourier transform, transfer function – Applications (vibration isolation from and to the environment, selection of machine foundation characteristics, principles of operation of vibration measurement devices) – Vibration of multi-dimensional linear discrete systems, modal frequencies and mode shapes, free and forced vibrations, modal analysis – Vibrations of one-dimensional continuous bodies (vibrations of strings, bars, beams, shafts) – Virtual Work, Lagrange Equations – Vibration measurements for machines and structures, methods of experimental estimation of modal characteristics – Approximate analysis methods (methods Rayleigh, Rayleigh-Ritz, Galerkin) – Machine dynamics (critical speeds, balancing).
