Course detail
FSI-RVHAcad. year: 2011/2012
Vibrations and noise are a general accompaniment to all machinery operations. The whole chain encompassing the vibration sources, transfer paths of the structure, noise emitters on the machine surface and ambient acoustic environment needs to be analyzed. We need to mainly focus on active methods of reducing vibrations and noise.Basic areas of examination:Spectra of vibro-acoustic quantities, experimental analysis, biomechanics of the human voice and hearing, acoustic properties of closed areas.Identification of sources of vibrations and noise, aerodynamic sources of noise.Passive methods of noise reduction.Active methods of noise reduction - vibroacoustic systems of machines, deterministic models (modelled by means of FEM ) for low-frequency noise), statistic models (solutions of high-frequency noise).
