Abstract

The forced oscillation acoustical diagnostics method consists of excitation of testing object forced resonant oscillation and processing of acoustical noise of the oscillations. The theoretical bases of the method are formulated with nonstationary excitation for vibroacoustical nondestructive testing of cracks in rotative blade systems. An analytical relation expressing the spectral density of testing object forced oscillations in terms of the relative crack size, damping factor, duration of NDT and parameters of nonstationary excitation is derived. Furthermore, a multidimensional vector of testing data for NDT of cracks invariant to parameters of nonstationary excitation is proposed.
