摘要

摘要:
为研究射流管伺服阀前置级劈尖的冲蚀变形对伺服阀工作性能的影响，采用Fluent仿真软件，对射流管伺服阀的前置级进行冲蚀仿真，并将仿真结果与冲蚀实物进行对比分析，发现劈尖是前置级冲蚀最为严重的部位；根据劈尖冲蚀前后的前置级结构形状，构建前置级的数学模型，分析了劈尖冲蚀变形对前置级压力的影响。利用AMESim仿真软件，搭建射流管伺服阀的整阀仿真模型，研究了劈尖冲蚀变形对整阀工作性能的影响；通过实验验证了AMESim仿真结果的正确性。研究结果表明，劈尖冲蚀变形后，射流管伺服阀前置级的恢复压力和负载压差减小，导致整阀的阶跃上升时间延长，幅频带宽减小，但整阀的空载流量特性和压力特性几乎不受影响。

Abstract:
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.
