摘要磨削加工是机械制造中重要的加工工艺，在机械制造中占有极其重要的位置。而在磨削加工中磨削热效应对工件的表面质量和使用性能影响极大，同时也会影响到砂轮的使用寿命。

本文在综述了磨削区温度场国内外研究现状的基础上，对磨削过程中磨削热的产生和分配、不同热源引起的磨削区温度场的不同做出了理论上的分析，并简要说明了有限元法在热分析中的应用及ANSYS软件在热分析中的重要步骤，最后以平面磨削为例，用ANSYS软件对磨削区温度场进行了仿真分析，并得出了一些结论如下：49606

（1）平面磨削时工件表层温度呈不均匀分布，磨削接触区温度最高，离磨削接触区越远，温度越低。

（2）砂轮转速、工作台进给速度以及磨削深度的不同，都会影响其磨削区温度场的结果。

Abstract Grinding is an important process in the machinery manufacturing, and occupies an important position in the machinery manufacturing. Grinding thermal effects in grinding the workpiece surface quality and performance of great impact, but also affect the life of the grinding wheel.

Made on the basis of the research status of the grinding zone temperature, the grinding process the grinding heat generation and distribution of different heat sources caused by the grinding zone temperature different theoretical analysis and a brief description of the application of the finite element method in thermal analysis and ANSYS software do importent step in the thermal analysis, surface grinding, for example, the grinding zone temperature field simulation analysis using ANSYS software, and draws some the following conclusions:

（1）The workpiece surface temperature was the uneven distribution of surface grinding, grinding contact zone temperature, the farther away from the grinding contact zone, the lower the temperature.

（2）Wheel speed, table feed speed and grinding depth different, will influence the grinding zone temperature.
