RESUMO

One- and two-dimensional vibrations of bound thin-walled structures excited by the spatially nonuniform convective field of random pressure fluctuations are studied. Expressions for the spectral density of generalized forces for sinusoidal forms of elastic system vibrations are obtained, and expressions are developed for estimation of the vibrational energy and power of the thin-walled structure sound radiation, depending on the characteristic parameters of the excitation field. General principles of the vibrations and of the acoustic radiation of the bound and unbound elastic systems are established.
