Abstract:
According to requirement of the engine system, a solenoid valve which has self-locking function with double station was needed to be developed to ensure that the engine can still work without electricity.As core component the electromagnet is the most important part of the self-locking solenoid valve, which directly affects the reliability of the whole valve.Application of double station self-locking electromagnet in engine is seldom before, there are inadequacies in design and simulation, and guidance are needed to be strengthened.In this paper, the working principle of a double station self-locking electromagnet was described and its magnetic circuit design formula and the method of magnetic field calculation were introduced.The simulation calculation of the self-locking electromagnet was carried out with the finite element analysis software.The experimental test verified the accuracy of the design.The influence of external parameters on the performance characteristics was obtained by conducting magnetic field simulation on the performance characteristics of electromagnets.Increase in armature working gap causes decrease in suction, increase in excitation voltage leads to decrease in response time and increase in trigger current & current reserve coefficient, which can enhance actuation margin.A design method of double station self-locking electromagnet which has engineering significance was obtained.This kind of electromagnet has been used in a liquid rocket engine and examined by thermal test many times.
