摘　　要：概述磨削过程建模与仿真的国内外研究现状,对基于经验分析、理论解析及有限元分析的三类建模与仿真研究发展历程与趋势进行综述,并对各类模型建立方法与仿真结果进行详细论述,同时深入分析这些模型应用的局限性,指出建立在有限试验数据基础上的经验模型预测水平较低;基于理想假设基础上的理论模型建模过程复杂;而由于技术问题,有限元法则仅限于对单颗磨粒磨削过程的仿真,有鉴于此,提出基于超硬磨粒有序排布砂轮的磨削过程建模与仿真方法,并进一步着重阐述其在高速高效磨削过程预测、优化与控制应用前景及意义。The research of the grinding process modeling and simulation is presented. The development progress and its tendency of three types of modeling methods and simulation are described results, which are based on empirical analysis, theoretical analysis and finite element technology. The method of modeling and simulating results are discussed respectively in detail. Meanwhile the limitations of application of models are analyzed. It is indicated that the empirical models are based on finite data of experiments, which have low level of prediction abilities, the theoretical models which are set up on ideal assumption is complexity, and the finite element models are restricted to analyze the process of single-grit grinding due to technical problem, on that account, the methods of grinding process modeling and simulation research based on the regular abrasive distribution grinding wheel are introduced. Furthermore, their present situation prospect and significance for prediction, optimization and control of high speed and high efficiency grinding are elaborated.
