Fault diagnosis of rolling bearings using a genetic algorithm optimized neural network
TL;DR: In this paper, the authors proposed an artificial neural network (ANN) based fault estimation algorithm was verified with experimental tests and promising results, every test was initiated with a reference ANN architecture to avoid inappropriate classification during the evaluation of fitness value.

A complex filter for vibration signal demodulation in bearing defect diagnosis
TL;DR: In this paper, a complex filter for Hilbert transform is proposed to apply in the real-time vibration signal demodulation for a roller bearing system, where three parameters, the scaling factor, center frequency and passband width, are designated to achieve the satisfactory properties of fast waveform convergence, constant passband gain and little phase distortion.

An analysis method for the vibration signal with amplitude modulation in a bearing system
TL;DR: In this paper, an envelope detection method for the vibration signal with amplitude modulation is proposed, which is based on the linear least squares analysis of the envelope signal and a logarithmic transformation is applied in this envelope signal.
