- Abstract
The jet pipe servo valve (jet valve) is the most widely used flow control servo valve on aircrafts and spacecrafts. However, the valve has not been simulated accurately due to its special structure and complex internal flow field. The structure design and performance analysis of the valve mainly rely on repeated experiments, which greatly limits the development efficiency of the valve. To solve the problem, this paper analyzes the magnetic field, flow field and structure field, all of which are involved in the working of the valve, one by one, and numerically simulate the coupling of the three fields. The simulated results were verified through experiments. Our method can greatly enhance the accuracy of jet valve simulation, providing a good reference to the simulation of various complex electrohydraulic devices.
