| 内容記述 | In order to effectively detect and identify the structure faults of rotating machinery, especially the precise diagnosis of structure faults at low speeds, in this study, we first proposed two kinds of dynamic model for shaft misalignment of rotating machinery as an entry point, the models will be used for vibration analysis of shaft misalignment state. Subsequently, we proposed a new kind of dedicated symptom parameters for structure faults of rotating machinery. Based on these symptom parameters, fault diagnosis method for structure faults of rotating machinery by multi-positional and multi-directional signals fusion and sequential successive multivariate analysis can be realized. The method can realize the detection and type discrimination of structure faults. Finally, we propose a precision diagnosis method that combines signal processing method which used empirical mode decomposition and sample entropy, with deep belief neural network (DBN). The advantage of this method is that the empirical signal decomposition method can be used to decompose the diagnosed signal into a plurality of intrinsic mode functions with high Signal to noise ratio (SNR), and then use the sample entropy as a criterion to screen the signals which containing a large amount of fault information. The screened signal are reconstructed into a new vibration signal. At last, the vibration signal is classified (precise diagnosis) by the deep learning method (DBN) which has strong pattern recognition function in the field of pattern recognition. The method has higher diagnostic precision than conventional methods. According to the experimental data measured by the rotating machinery in the abnormal states of each structure faults, the effectiveness of each method will be verified. |
