The article presents the results of research of orthogonality of the signals of vibration acceleration, vibration velocity and vibration displacement in the course of the defect development by means of numerical simulation of defects and correlation analysis.
Orthogonality of diagnostic features is an important condition that significantly simplifies the process of vibration analysis of the equipment condition. The more independent characteristics form a vector of diagnostic features, the easier to relate it to the vector of the equipment condition.
The dependence of the equipment condition is simplifying if all diagnostic features of a vector are orthogonal.
