【摘要】 基于动压润滑理论,建立了浇注法方式下磨削区流场的光滑数学模型并利用多重网格法计算出了磨削区流场的动压力和流体速度;在光滑模型的基础上建立了考虑砂轮和工件表面粗糙度的粗糙模型并利用多重网格法得到该模型下的解。结果表明:粗糙模型得到的磨削加工区流体的动压力及流速曲线是不光滑的,但光滑模型和粗糙模型的解吻合较好。更多还原

【Abstract】 By using hydrodynamic lubrication theory,the mathematical model of grinding fluid field in flood was set up,and hydrodynamic pressure and velocity of grinding fluid were calculated by multigrid method.The crude model considering the roughness of grinding wheel and workpiece was built based on the slick model and the solution was obtained by multigrid method.The result shows that the curves of hydrodynamic pressure and velocity of grinding fluid obtained by crude model are unsmoothed,and the solution of slick model is in good agreement with that of crude model.更多还原
