In mechanical systems, the role of rolling element bearings is pivotal, as their vulnerability to various faults emphasizes the potential for performance decline, increased maintenance costs, and potentially catastrophic failures. To address these issues, this study focuses on leveraging Artificial Neural ...

In most cases, gears and rolling bearings are running with high speed, heavy load or high temperature. Hence, the fault signal always has the characteristics of nonlinearity, nonstationary and non-Gaussian. Therefore, how to conduct the fault feature extraction from the non-stationary vibration ...
