Abstract: In the paper, an analysis of the spread of intensity of wavelet of a mechanical object (a metal structure of a bridge) and its parameters is carried out upon application of the theory of covariance functions. The results of measuring the intensity of vibrations in fixed points were recorded on the time scale in a form of data arrays (matrixes). The estimates of covariance functions between the arrays of digital results in measuring the intensity of vibrations and the estimates of covariance functions of single arrays were calculated upon changing the quantization interval on the time scale. In the calculation, software Matlab 7 was applied.
