摘要
利用Gambit和Fluent对伺服阀衔铁组件的啸叫问题进行CFD分析,模拟计算产品内部油路结构的流固耦合,发现在伺服阀衔铁组件啸叫时,流体在产品内部产生了卡门涡。改变产品的内部结构再次进行CFD模拟计算,卡门涡消除;对该结构的产品进行实际的同压通液测试,伺服阀啸叫的问题得到解决。
By using Gambit and Fluent to carry on the computer flow dynamics （CFD） analysis for the whistling problem of ser- vo valve armature module, the flow and solid coupling in the interior oil duct structure was simulated. It was found that Carmen whorl was produced in the product interior when servovalve armature module whistles. By changing product internal structure and carrying on CFD analog computation once more, the Carmen whorl was eliminated. Through making actual passing fluid test under same pressure to this structure＇s product, the whistling problem of the servo valve is solved.
