Abstract
In order to obtain an optimization design of jet pipe hydraulic servo valve feedback components. The authors made theoretical derivation about the structure and properties of feedback components on the jet pipe servo valve. In view of the mathematical derivation of the feedback lever stiffness is not accurate, we focused on the finite element analysis about curvature of the feedback lever. The best bending angle of the feedback leveris was determined as 135°, the feedback force enhanced by 8.6% relalively to any other angle. This work makes the design ideas about the feedback components clearly. Then, a finite element analysis model was used to simulate the spool and the jet pipe nozzle displacement when the electromagnetic torque acting on thearmature components. The relationship among torque, spool and the jet pipe nozzle was summed up.
