Elements of the statistical system for vibration tests of machine

Presented considerations of this work includes selected issues in the area of statistical procedures use in vibration measures study and modal analysis methods to assess the machines state. The indicated statistical procedures are particularly important in vibration and modal research, where the multidimensionality of diagnostic signals requires a wide application of various statistical procedures at the stage of processing and decision-making. This paper presents the MATLAB program for determination of the Symptoms matrix, software tools for reading and exporting files to the unv format, the OPTIMUM computer algorithm, the Singular Values Decomposition (SVD) computer algorithm and the state matrix analysis program using the MAC theory.
