摘　　要：提出一种新型液动压悬浮抛光方法,阐述液动压悬浮抛光的基本原理,通过对结构化单元的划分及其流体液动压力的研究,推导出液动压承载力与抛光液黏度、抛光工具速度、抛光间隙以及抛光工具盘结构参数如单元长度、单元宽度、形状系数等的解析模型。数值模拟研究获得了影响液动压悬浮抛光工具盘承载力大小的主要因素,液动压抛光工具盘的斜面升高比和斜面占长比对承载力的数值大小存在极值条件,承载力与抛光工具盘速度和单元长度成正比,承载力与单元宽度的平方成正比并与加工间隙的平方成反比,单元宽度和加工间隙对承载力数值大小的作用最为显著。Based on the hydrodynamic lubrication mechanism, a novel hydrodynamic suspension polishing method is proposed. Principle of hydrodynamic suspension polishing is introduced. According to the slicing of cell structures and analysis on the fluid hydrodynamic pressure, analytical model between suspension force capacity and liquid viscosity, velocity of polishing tool, polishing film thickness, structural parameters of polishing tool including cell length, cell width, shape factor. Effect of main parameters on the value of suspension force capacity during hydrodynamic suspension polishing are compared by numerical simulation. There are extremal condition between suspension force capacity and inclination taper ratio couple with inclination length ratio of polishing tool. Suspension force capacity are in direct proportion to rotational speed of polishing tool and hydrodynamic unit length. Suspension force capacity is in direct proportion to squared hydrodynamic unit width and in inverse proportion to squared polishing gap. The most significant effect are hydrodynamic unit width and polishing gap for the suspension force capacity.
