Abstract

The multi-source dynamic feature recognition of mechanical nonlinear multi-failure mode is a technical bottleneck and problem encountered in the application of fault diagnosis in the process industrial production line. It needs not only to extract the time-frequency characteristics of the single-source fault signal but also to ensure the corresponding relationship between the nonlinear variable, multi-fault mode and multi-source fault features in time, frequency and space after feature extraction. Mechanical multi-source signals also have coupling, aliasing, and other phenomena that cause the characteristic signals between the channels to interfere with each other and overlap. In order to meet the requirements of automatic monitoring and fault diagnosis of industrial process production lines, this paper develops multi-source dynamic feature recognition and adaptive diagnosis. This paper studies the multi-scale parallel factorization theory and proposes a three-dimensional time-frequency space model reconstruction algorithm for multi-source feature factors, which improves the accuracy of mechanical fault detection and intelligent levels
