摘要

The grinding depth of a definitive tool for fixed abrasive grinding processing could be controlled continuously by controlling the thickness of the liquid membrane between the workpiece and the grinding pad.So,hydrodynamic grinding theory research on fixed abrasive processing was proposed for the first time.The liquid membrane played an important role,therefore,the transient isotherm hydrodynamic lubrication equations of the liquid membrane between the tool and workpiece were established.Then explicit difference algorithm was adopted.The numerical simulation was conducted to analyze the hydrodynamic pressure and its distribution The feasibility of controlling the grinding depth by liquid membrane’s hydrodynamic pressure was confirmed by the simulation result Because of the dissection from the particles,the liquid membrane could not be successive which will create the local pressure peak and it will affect the membrane’s pressure-bearing effect.Fluid-structure interaction was proposed in this paper to optimize the simulation result The deformation of the pad’s organism near the pressure peak areas was being considered.Deformation equation and deformation matrix from elasto-hydrodynamic lubrication was used for coupling the liquid membrane pressure and the deformation.After the optimization,the pressure peak decreased observably and the membrane’s pressure-bearing effect was improved
