Researches and Simulations on Hydrodynamic in Super High Speed Grinding Area

摘要

It analyzed the conditions in hydrodynamic action of coolant in super high speed grinding area and described the conception of lubricate induce force in the paper. Using fluid dynamical lubrication theory, theory analyses and mathematics modeling on lubricate induce force in plane grinding with non-porous grinding wheel were carried out, also the computer simulations were done, and the conclusion was theoretically verified by tests in interrelated material documents. On the bases of this, by analyzing the effects of parameters and pointing out grinding wheel speed, grinding wheel width significantly influences the max dynamic pressure in grinding area, thus the analyses indicated that it rises with the speed of grinding wheel increasing.
