AB - The characteristics of film flow field have important effects on the quality of hydrodynamic polishing.
Oriented preparation requirements of amorphous film substrate, in order to further study the floating
height of hydrodynamic polishing base plate in working conditions, the mathematical model is established
and the theoretical analysis has been carried out for the wedge hydrodynamic floating polishing base
plate. The relationship between buoyancy and floating height is researched. The floating height is
calculated under the known loads, and then the pressure distribution along the circumferential direction
of base plate is analyzed. Film flow field is simulated and analyzed using the FLUENT based on the
calculated floating height. It indicts that the bearing capacity of wedge combination plane decreases
with the increase of floating height, and the downward trend slows down gradually. The pressure peak
distributes near the interface of wedge flow field and parallel flow field. Through the pressure distribution
comparison of simulation and calculation, the correctness of the mathematical model and simulation
method is verified.
