scholarly journals Hasty Fault Diagnosis of a Rotating Machinery Hinge on Stalwart Trippy Classifier with Robust Harmonized Swan Machine

Monitoring with fault diagnosis of machineries are critically important for production efficiency and plant safety in modern enterprises. Along the process of fault diagnosis due to the addition of faulty signals, it is not an easy task to extract the exact representative features from the original signal. Accordingly, for making the vibration signal analysis more effective, there is a need to have the proper faulty feature extraction and moreover to have the proper estimation of spectral density for eminently producing stable decomposition results even if the signal contains missing values. Moreover, there is a difficulty to measure the correlation between the features with the existing fault diagnosis researches and also it considers more learning time as well as memory constraints which makes the learned concept difficult to understand for classifying the faulty features prominently. Thus to commensurate a perfect diagnosis, in this research a “Robust Harmonised Swan Machine (RHSM) with Stalwart Trippy classifier” is formulated in which the iterative estimation of each mode satisfying a self-consistency nature in decomposition method of RHSM which in turn resolves the missing sample problem eminently and aids reinforcement learning precisely which measures the correlation between the features to classify the faulty features extremely thereby it takes only less memory constraint with less learning time.

In order to improve the diagnosis method of the existing high-voltage circuit breaker fault, demonstrated a new diagnosis methord of mechanical failure of high voltage circuit breaker based on vibration signal. According to the factors of high voltage circuit breaker failure and the features of Single-hidden Layer Feedforward Neural Network, SLFN, a method of high voltage circuit breaker fault diagnosis proposed based on Extreme Learning Machine (ELM). Finally, the experiment proves the effectiveness of this method for breaker fault diagnosis based on vibration signal analysis and ELM.

In order to monitor the operation state and implement fault diagnosis of rolling bearing in rotating machinery, this paper presents a method of fault diagnosis of rolling bearing, which is based on EMD and resonance demodulation. Using EMD to decompose the signal, which comes from QPZZ-II experimental station, the components of intrinsic mode function (IMF) will be obtained. Then, calculating the correlation coefficient of each IMF component, the highest correlation coefficient of IMF component will be analyzed by resonance demodulation. Finally, the experimental results show that the method can accurately identify and diagnose the running state and bearing fault type.
