| 中文摘要: |
| 分析了盘式翼型悬浮抛光（ASP）的液动压分布规律，推导了工件盘和抛光盘不同心角速度反向等速条件下的液动压数学模型。对盘式翼型悬浮抛光流场进行了数值模拟，揭示了抛光盘和工件盘的运动关系以及抛光盘不同翼型曲线和迎角对流体动压力的大小和均匀性的影响规律。研究表明，当抛光盘和工件盘反向旋转时的流体动压力均匀性明显优于同向旋转，且当转速比为-1时流体动压力分布的数值模拟效果最佳；当选用NACA 16018翼型曲线、迎角为0°时，液动压带的面积数值效果最优。 |
| 英文摘要: |
| Distribution of hydrodynamic pressure during airfoil suspension polishing (ASP) process are analyzed, by using hydrodynamic pressure mathematical models deduced when considering eccentric, constant angular velocity and reverse rotation between workpiece plate and polishing plate. Flow field of airfoil suspension polishing is numerically simulated, and motion relationship between disc polishing and workpiece disc, as well as effect of airfoil curves and attack angles of polish plate on magnitude and uniformity of hydrodynamic pressure, is declared. Results suggest that uniformity of hydrodynamic pressure when using co-rotating mode is better than that of eccentric rotating between workpiece plate and polishing plate. Best uniformity of hydrodynamic pressure distribution is gotten when rotational speed ratio is -1. Best hydrodynamic pressure band distribution is found when using NACA 16018 airfoil curve with 0° attack angle. |
