摘　　要：针对平面磨削力建模存在的磨粒形状复杂、数量多等难题,采用量纲分析和有限元的方法,建立球形、正四面体、正八面体和正十二面体四种单颗粒磨削仿真模型,以研究不同磨削用量和磨粒形状对磨削力的影响规律。在仿真结果的基础上,建立了平面磨削力预测模型,并通过18CrNiMo7-6合金钢平面磨削试验对预测模型进行验证。结果表明:法向和切向磨削力与切削深度正相关,法向和切向磨削力的试验值与模型预测值的相对误差均在9.75%以内。模型能够有效地预测平面磨削过程中的法向力和切向力。To address the challenges of modeling plane grinding forces,such as the complexity of abrasive particle shapes and their large number,we used dimensional analysis and finite element methods to establish four single-particle grinding simulation models:spherical,regular tetrahedron,regular octahedron,and regular dodecahedron.These models were used to study the impact of different grinding parameters and abrasive particle shapes on grinding forces.Based on the simulation results,a model was established to predict plane grinding forces,which was then validated through plane grinding experiments.The results show that normal and tangential grinding forces are positively correlated with cutting depth,and the relative errors between the experimental and predicted values of these forces are within 9.75%.Thus,the model effectively predicts the normal and tangential forces in plane grinding.
