【摘要】：基于超精研过程中圆锥滚子与油石接触的几何特点及磨削原理,建立数学模型包括单位面积动态有效磨刃数模型和整体动态有效磨刃数模型,估计参数取值并用MATLAB运行模型,分析关键因素对磨刃分布的影响。超精研区不断变化的滚子半径是引起磨刃数动态变化的主要因素;受到滚子与油石径向接触弧长的影响,单位面积动态有效磨刃分布与整体动态有效磨刃分布完全不同;油石振荡频率对整体磨刃分布的影响最明显。若考虑磨削深度随滚子与油石接触面积的变化而变化,可以得到理想的"对号"形磨刃分布。
[Abstract]:Based on the geometric characteristics and grinding principle of contact between cone roller and oil stone during superfine grinding, a mathematical model is established, which includes dynamic effective grinding edge number model per unit area and global dynamic effective grinding edge number model. The parameters are estimated and run with MATLAB model. The influence of key factors on the distribution of grinding edge is analyzed. Under the influence of radial contact arc length of roller and oil stone, the dynamic effective edge distribution of unit area is completely different from that of the whole dynamic effective edge distribution. The oscillation frequency of the stone has the most obvious influence on the distribution of the whole grinding edge. If the grinding depth varies with the contact area between roller and stone, the ideal "logarithmic" edge distribution can be obtained.
