THE PRINCIPAL REGULARITIES IN ELASTIC SYSTEM VIBRATIONS AT NONUNIFORM AEROACOUSTIC EXCITATION
RESUMO
The key physical phenomena and principles defining thin-walled elastic system vibrations at nonuniform random dynamic excitation are studied. The relations between spatial nonuniformity scales, correlation scales, and phase velocity of the exciting field spectral components, wavelengths in elastic systems, and the expansion velocity of the waves in which these physical phenomena are revealed are defined. We also discuss the nature of the revealed effects of the vibration amplification. The analytical expressions are obtained for estimation of the spectral density of the elastic system vibration.
