Abstract :
This paper brings forward a mathematical stiffness model of feedback spring pole in jet pipe electro-hydraulic servo-valve. The feedback spring pole is identified as more critical spring elements in servo-valve operation. If this element is properly designed with respect to stiffness, automatically dynamic performance of the servo-valve is improved. Mathematical model of optimal stiffness of the feedback spring is established. Furthermore an attempt has been made to predict stiffness of this element by finite element method.
