Fault Simulation and Diagnosis Technology of Hydraulic System for Hydraulic Support

Aiming at the problem that it is difficult to obtain fault data in the fault diagnosis of support hydraulic system, a fault diagnosis method based on fault simulation is proposed.Based on the analysis of the working principle and common faults of the support hydraulic system, AMESim software is used to simulate the common fault conditions of the support hydraulic system and collect sample data. The fault diagnosis algorithm of BP neural network is used to carry out fault simulation training and diagnosis test through MATLAB software. The diagnosis results show that the method has high accuracy and reliability, achieves the expected goal. It can be used in the fault diagnosis of support hydraulic system and lay a research foundation for further intelligent fault diagnosis and health monitoring of support hydraulic system.
