Abstract

The hydraulic system of the hydraulic support truck for coal mines is prone to failure during operation, and the failure of the hydraulic system is not handled in time, which has a serious impact on the safety construction of coal mining projects. Aiming at this problem, a new fault diagnosis method of hydraulic system is proposed. According to the working principle of the hydraulic system of the hydraulic support truck, establish a mathematical model for fault diagnosis of the hydraulic system; extract the fault time domain signal characteristics of the hydraulic system, and obtain the mean and variance of the fault samples; analyze the operating state and operation mode of the hydraulic support truck, and analyze the internal hydraulic system. Comprehensive fault diagnosis. Through the experimental analysis, it can be seen that the designed hydraulic system fault diagnosis method can quickly complete the fault diagnosis in a short time, and the accuracy of the diagnosis results is above 95.27%, which is highly feasible.
