Abstract EN
Data measurement of roller bearings condition monitoring is carried out based on the Shannon sampling theorem, resulting in massive amounts of redundant information, which will lead to a big-data problem increasing the difficulty of roller bearing fault diagnosis.
To overcome the aforementioned shortcoming, a two-stage compressed fault detection strategy is proposed in this study.
First, a sliding window is utilized to divide the original signals into several segments and a selected symptom parameter is employed to represent each segment, through which a symptom parameter wave can be obtained and the raw vibration signals are compressed to a certain level with the faulty information remaining.
Second, a fault detection scheme based on the compressed sensing is applied to extract the fault features, which can compress the symptom parameter wave thoroughly with a random matrix called the measurement matrix.
The experimental results validate the effectiveness of the proposed method and the comparison of the three selected symptom parameters is also presented in this paper.
