摘要： 采用数值仿真和实验研究相结合的方法，分析了WC-Co高硬度涂层磨削温度场.以矩形移动热源理论为基础，结合实验加工条件和工件材料性质，通过合理的假设简化，建立了金刚石杯形砂轮磨削WC-Co高硬度涂层材料的温度场数学模型，利用有限元方法对磨削温度场进行了数值仿真，提出了涂层磨削温度的实验测量方法并对涂层表面磨削温度进行了实验研究.实验结果与仿真结果基本一致，表明所提出的高硬度涂层温度场数值仿真和实验研究方法能比较真实地反映WC-Co涂层材料在磨削过程中的温度变化情况.

Abstract: Through both of numerical simulation and experimental study, the grinding temperature field of WC-Co high hardness coating was analyzed. Based on the moving heat source theory, combining with the grinding conditions and the property of the workpiece, the temperature field model of diamond cup wheel grinding of WC-Co coating material was established and simplified through appropriate assumption. FEM (Finite Element Method) based numerical simulation of WC-Co coating grinding temperature field was then performed. A novel coating grinding temperature measurement method was proposed to experimentally research the grinding temperature. A good agreement has been achieved between the simulation and experiment, which shows the proposed methodologies can be effectively applied to analyze the coating grinding temperature and provide a means for research on the high hardness coating grinding mechanism.

Key words: WC-Co coating, grinding temperature field, finite element method, numerical simulation
