The paper presents a method of creating a multi-valued diagnostic model using Wigner-Ville transformation of vibroacoustic signals measured on a real object. The result is a transformation matrix in which the rows correspond to the frequencies F and the column - times T of successive samples of the signal. Integer coding involves assigning values to the coefficient specified range of real numbers one integer. After applying the coding a multi-valued diagnostic model is obtained. The model describes the relationship between a set of significant frequencies, rms values of Wigner-Ville transform’s coefficients, and a set of diagnosed object failures.
