| Abstract: | We analyze the dynamic flow field of double nozzle baffle electro hydraulic servo valve prestage, research the change of the prestage flow field by deflection of loaded armature baffle components, analyze the change of velocity, pressure, power loss of fixed choke, nozzle, return port, and the displacement, stress of armature baffle components, the valve core of slide valve. The FSI method is adopted to analyze the flow field of double nozzle baffle electro hydraulic servo valve prestage through the software Ansys, which provides an analytical method for analyzing the flow field of double nozzle baffle electro hydraulic servo valve to obtain more accurate analysis results, and a guidance for the choice of structural parameters of the model and solid materials. |
