摘　　要：用液固两相流体动力学的方法对离心研磨过程中磨料流的运动特征进行数值模拟,得出磨料流运动的动态结果,并与高速摄影实验结果进行对比,指出计算机数值模拟结果对研磨机的设计和研磨工艺参数的选择具有实际的指导意义。该方法经济简捷,可以代替大量的工艺实验实现对离心研磨技术参数的优化,从而提高生产效率。A method of two-phase fluid dynamics was advanced, which simulated numerically the kinematic behavior of the abrasive fluid in planetary lapping process. Dynamic results from the method are contrasted with the profiles of the moving abrasives during planetary lapping obtained by high-speed photographic experiments. The facts of two similar results show a lot of technical experiments can be substituted by numerical simulation with computer. The parameters of design and technology can be optimized economically and efficiently with the method so as to improve productivity.
