摘　　要：提出一种液动压悬浮抛光加工新方法,该方法是基于流体动压润滑理论,以高速转动的抛光盘带动抛光液及其磨粒对工件表面进行加工。针对动压浮离抛光过程中存在的表面压力分布不均的问题,在动压浮离抛光盘的基础上加入约束边界和蓄流槽,设计一种新型抛光盘,实现了液动压悬浮抛光。利用CFD软件对抛光盘与下盘面间的流场进行数值模拟,得出动压浮离抛光盘和新型抛光盘底部流道的液体压力分布。结果表明,新型抛光盘能够能提高加工区域的流体压力,并能使流体压力的分布相对均匀。A new hydrodynamic namic lubrication theory, uses the suspension polishing method was put forward.This method is based on fluid hydrody- polishing process of the surface of workpieees.In o new type of polishing disc was designed disc at high-speed rotation to drive the slurries and abrasives and realize the rder to resolve the nonuniform distribution of surface pressure during polishing, a by adding constraint boundary and storage chute based on the hydrodynamic-type polishing disc, and the hydrodynamic suspension polishing lower disk was simulated by using CFD software,the distil for the hydrodynamic-type polishing disc and the new new hydrodynamic suspension polishing tools disc can pressure distribution relatively uniform was realized.The flow field between the polishing disc and the bution of fluid pressure at the bottom channel of polishing disc hydrodynamic suspension polishing disc. The results show that the improve the fluid pressure in the processing region, and make the pressure distribution relatively uniform.
