Abstract:

Solenoid valve is an important component of aeroengine digital electronic control system， and its rapid response is an important factor which restricts the performance of aeroengine digital electronic control system. A mathematical model of a solenoid valve is built based on the design principle of a certain type of aviation solenoid valve， and the design parameters and actual test and test data are used to verify the mathematical model of the built aviation solenoid valve. The verification results show that the designed mathematical model of solenoid valve has high dynamic and static accuracy. On this basis， an optimization method of aviation solenoid valve based on adaptive simulated annealing algorithm is designed， and the four important parameters of solenoid valve including coil turns， spool quality， initial working air gap width and model tube diameter were optimized. The research results confirmed that， compared with the original design， the solenoid valve opening response time after parameter optimization was shortened by 50%， and the closing response time after parameter optimization was shortened by 45.4%.
