| Abstract: | A mathematical stiffness model for the feedback spring pole in the jet 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 thefinite element method. |
