Design and Modelling of a Hydraulic System for Detecting Solenoid Valve Based on Bond Graphs Method

摘要

A novel system is developed in this paper for detecting solenoid valve which is a key component in many industries as automobiles, power equipment, chemical engineering, etc. The numerical model of system is developed by the Bond graphs method, which is widely utilized because they enable easy identification of the parameter process and consider interactions within the hydraulic system. The system model is divided into mechanical section, hydraulic section and electromagnetic section and established to analyse the dynamic performance of the system respectively. Simulations are implemented to verify the rationality of the designed system. In the end, it demonstrates that the simulations results are consistent with the pressure control law of solenoid valve, and the designed system can meet the detecting requirements of solenoid valve.
