中文摘要: 电液压力伺服阀是电液压力伺服控制系统的核心控制元件，广泛应用于航空、航天、军事等领域。区别于流量伺服阀，压力伺服阀在滑阀放大器的设计上多采用带有压力控制容腔的三通阀结构，不同的滑阀结构使得现有的偏转射流流量伺服阀仿真模型难以满足压力伺服阀性能预测的需求。本文基于AMESim平台建立了偏转射流压力伺服阀的仿真模型，并通过实验对仿真模型进行了验证，验证结果表明仿真模型能够准确地描述压力伺服阀的静态特性。最后，通过仿真模型分析了加工装配误差影响下压力伺服阀输出性能差异，仿真结果可为偏转射流压力伺服阀的性能预测和结构设计提供参考。

Abstract:As the core component of electro-hydraulic servo control systems, pressure servo valves are widely used in aviation, aerospace, and other related fields. Because the three-way valve structure with pressure control chamber is adopted in the design of pressure servo valve, the existing simulation model of deflector jet servo valve can’t accurately predict the performance of deflector jet pressure servo valve. To investigate this issue, the paper establishes a new deflector jet pressure servo valve simulation model based on the AMESim platform. In addition, the simulation model is verified by experiment. The verification results show that the model can accurately describe the static characteristic of deflector jet pressure servo valve. Finally, the performance difference of pressure servo valves under different machining and assembly errors is analyzed based on the simulation model. The analysis results provide a reference for the structural design of the deflector jet pressure servo valve.
