With an increasing demand for hydraulic pumps in the era of Industry 3.0 and 4.0 due to their higher performance, they are getting compact and thus more vulnerable to leakage due to tight tolerances. Thus, it is imperative to diagnose these faults at the early stage. In this study, an attempt has been made to diagnose the internal leakage of hydraulic pumps using an …

Due to the nonlinear characteristics of hydraulic systems under noisy working conditions, it is difficult to extract fault features from vibration signals collected from the surface of the valve body. Therefore, a DSmT-based three-layer method using multi-classifier is proposed to detect multiple faults occurred in hydraulic valves.
