| Abstract: | This paper derives a mathematical expression of steady-state fluid force in the valve spool based on the structure and operation principle of direct drive servo valve sith rotary spool, carries out the simulation and computation, and draws some useful conclusions. These conclusions have very good instructiveness for optimal design of the valve structure, the selection and design of drive mechanism of valve spool and the characteristic analysis of servo |
