强化研磨中喷头的改进及优化设计

在强化研磨过程中,为了能对轴承内沟道进行喷射处理,将喷头出口处设计为弯型,同时为使研磨料经过弯型喷头时能量损失最小,需设计合理的弯道半径及弯管角度。运用Pro/E建立15种不同弯道半径及弯管角度情况下的CAD模型,然后导入ANSYS数值模拟分析相同初始条件下各个喷头PROE模型的内部流场压力云图。结果表明:最优值即弯角θ=20°,弯管的曲率半径R=30 mm时能量损失最小。

Improvement and Optimization Design of Nozzle in Strengthening Grinding

In the process of strengthening the grinding , in order to to spray the bearing inner channel , the nozzle exit was de-signed for bending .To minimize the energy loss at bending when grinding material passed , design of the bend radius and bend angle of bending nozzle reasonablely was needed .Pro/E was used to establish 15 kinds of different bend radius and bend angle of computer ai-ded design ( CAD) model, and then the ANSYS numerical simulation was introduced to analyze the inner flow field pressure cloud ima -ges of these nozzles under the same initial conditions .It is concluded that the energy loss is the smallest when the optimal value is bend angle θ=20°, and bend radius of curvature R=30 mm.
