摘　　要：针对力反馈式射流管伺服阀动特性不易预测的难题,通过采用建模仿真的方法来预测及优化力反馈式射流管伺服阀的动特性。建立了力反馈式射流管伺服阀的数学模型,通过仿真试验研究,分析了其时域特性和频域特性。最后在此基础上,通过优化滑阀的结构、降低反馈杆刚度及衔铁组件的转动惯量等方面,提升力反馈式射流管伺服阀的工作性能。仿真试验结果表明,优化后的力反馈式射流管伺服阀的动态性能得到了极大改善。研究结果为提高力反馈式射流管伺服阀动态性能提供了参考。In the view of the problem of hard to predict the dynamic characteristics of the forcefeedback jet-pipe servo valve,based on the method of modeling and simulation to predict the dynamiccharacteristics of the jet pipe servo valve system,firstly,mathematical model of the feedback jet-pipeservo valve is modeled, and then the time domain and frequency characteristics by simulationexperiment is analyzed. Finally,through the structure optimization of the slide valve,inertia feedbackstiffness and armature assembly performance of the power system are reduced to improve the dynamiccharacteristics of the force feedback jet-pipe servo valve. The simulation results show that this methodis effective and the research results provide reference for improving the dynamic performance of theforce feedback of jet-pipe.
