Abstract

The reliability of solenoid directional valve has great influence on the working performance of hydraulic system. Based on the fault analysis of the solenoid directional valve, the typical fault of the valve core not acting is studied. Through the modeling and simulation of the dynamic characteristics of the solenoid directional valve, the current and displacement signals that can be used as the real-time fault monitoring parameters of the solenoid directional valve are extracted, and the current and displacement signals of the energizing and closing section of the solenoid directional valve under different states are simulated, which verifies the rationality of the selected two fault monitoring parameters, and provides the basis for the construction of the real-time fault monitoring system of the solenoid directional valve.
