To study the influence of the erosion deformation of the pre-stage wedge on the working characteristics of the jet pipe servo valve, the erosion simulation of the pre-stage is carried out by Fluent simulation software, and the simulation result is compared with the erosion object, which shows that the wedge is the most serious erosion part in the pre-stage. The mathematical model of the pre-stage is constructed in accordance with the structural shape of the pre-stage prior to and following wedge erosion, and is used to examine the impact of the wedge erosion deformation on the pre-stage pressure. The simulation model of jet pipe servo valve is built based on AMESim simulation software, and the influence of wedge erosion deformation on the working characteristics of jet pipe servo valve is further studied. Finally, the correctness of AMESim simulation results is verified by experiments. The outcomes demonstrate that the recovery pressure and differential pressure of the pre-stage can decrease after the erosion deformation of the wedge, which results in an increase or decrease in the step-up time and amplitude-frequency bandwidth of the jet pipe servo valve, respectively. However, the unload flow characteristic and pressure characteristic of the servo valve are essentially unaffected.
