Aimed at the bad performance of large quantity of calculation and slow computing speed of the traditional method of three-band enveloping demodulation

a bearing fault detection method based on Peakvue technology is presented. The vibration signals including stress waves are collected by acceleration sensor. The peak values are extracted at a certain rate from the signals after through a high-pass filter because of transient stress waves. The signals are demodulated to determine the fault type. Matlab simulation results show that the proposed method has improved the performance in both detection speed and diagnosis accuracy.
