摘要
利用Fluent对气动电磁阀的三维稳态流场进行仿真,流场仿真结果表明,现有结构的气道1与气道2相贯处流场变化剧烈,压力损失较大。扩大气道1孔径以增大相贯处的通流截面积,减少压力损失,平缓流场,增大了通过电磁阀的空气流量。制作样品,并对样品改进前后的流量进行实际测量,验证数值仿真的正确性。
This thesis applies Fluent to simulate the 3D steady flow field of pneumatic electromagnetic valve,and the simulation results indicates that the flow field changes tempestuously of the intersecting of air-passage 1 and air-passage 2,and large pressure-loss.It raises flow rate of valve withing enlarging the diameter of air-passage I to expand the area of the intersecting, make less pressure-loss and ease the flow field.In order to check the simulation results,it maks samples and measurs flow rate before improving and after.
