A transparent model is used to make the deflection jet board grounded on the inhere enlarged dimensions. the finished experiments are conducted to catch the flow rate directions and the situation of cavitation using a high - speed video cameras. in this paper, the finite element analysis and visualiation research of servo valve prestage jet flow field are carried out, which establish the theoretical foundation for mathematical model of servo valve prestage and the whole mathematical model of hydraulic servo valve
在對射流前置級驅動的伺服閥射流流場數值模擬的基礎上，用有機玻璃在偏導射流板原始尺寸的基礎上進行了擴大，製作了透明的偏導射流板，運用高速攝像機、液壓泵站等組成了可視化實驗系統，對射流流場的流速方向、渦流、氣穴等現象進行了多方位的觀測，並通過對接收管接收壓力的測試，對流場分析結果進行了驗證。 -
Because of the jet flow field for the prestage of hydraulic servo valve driven by jet flow, it is difficult to build an accurate mathematical model, thereby the analysis of servo pipe and whole servo control system is difficult to be carried out
由射流前置級驅動的伺服閥，由於射流流場的不確定性及流場分佈的復雜性，因而很難建立精確的數學模型，從而使伺服閥及整個伺服控制系統的分析難以實現。 -
In this paper, field of servo valve prestage is simulated and tested. the 2 - d geometric model of the jet flow field is established by utilizing the cad software autocad, according to the parameter of practical size. the mesh of the model is generated by gambit which is the preprocessor of the fluent software
本論文針對伺服閥前置級射流流場的流動情況，按照實際使用中伺服閥前置級的參數，應用cad軟體autocad建立二維幾何模型，運用fluent前處理軟體gambit進行了網格的劃分。 -
