摘　　要：建立了射流管伺服阀反馈杆的刚度数学模型.射流管伺服阀反馈杆为特殊的弹簧元件,可以通过恰当地设计反馈弹簧来实现射流管伺服阀的良好动态特性.同时还构建了反馈杆刚度的优化模型,通过有限元分析进行反馈杆刚度的分析和预测.A mathematical stiffness model for the feedback spring pole in the 3et pipe electro- hydraulic servo-valve is constructed. The feedback spring pole is a special spring element in servo-valve operation. If it is properly designed with respect to stiffness, the dynamic performance of the servo-valve is improved. A mathematical model of optimal stiffness of the feedback spring is established. Meanwhile, an attempt was made to predict its stiffness with the finite element method.
