摘要磨削是现代机械制造业中进行精密加工、超精密加工，对不锈钢、高温合金、钛合金、工程陶瓷等难加工材料进行加工的重要手段。磨削过程中磨削热效应不仅影响到砂轮的使用寿命，而且对工件的表面质量和使用性能影响极大。因此对磨削温度场的研究非常重要。 47440

   本文在综述磨削区温度场国内外研究现状的基础上，对磨削区温度场的计算做出了理论上的分析，并用有限元分析软件ANSYS对钛合金平面磨削温度场进行了仿真分析与比较。结果表明在同种冷却条件下，要想在保证生产效率的前提下降低磨削区温度，应该采用较小的砂轮转速和磨削深度，并适当提高工件移动速度。具体研究内容如下：

（1）查阅相关文献对磨削加工以及磨削区温度场热源模型进行理论学习，并用热源法对磨削区温度场进行了分析研究，然后理论上建立了温度场的数学模型，并确定了平面磨削时的热源形式。

（2）进行有限元法与有限元分析软件ANSYS的学习。学习ANSYS热分析从建模、求解到后处理。为后期对磨削区温度场仿真做好准备。

（3）用ANSYS对钛合金平面磨削加工模型进行仿真，以及改变加工工艺参数（砂轮转速、磨削深度、工件移动速度）进行仿真，并对仿真结果进行比较分析得出结论。

Abstract Grinding machine manufacturing industry is the modern for precision machining,

the ultra precision processing, to the stainless steel, high temperature alloy, titanium alloy, engineering ceramics to processing materials for machining the important means. The grinding process grinding heat effect not only affect the service life of the grinding wheel, and the surface of the workpiece quality and performance greatly influence. So the grinding temperature field of study is very important.

This paper reviewed in grinding zone temperature field research situation, on the basis of the calculation of temperature field in the grinding zone to make a theoretical analysis, finite element analysis software ANSYS and titanium alloy plane grinding temperature field simulation analysis and comparison. The results show that the same cooling conditions, in order to ensure the production efficiency under the prerequisite of the lower the temperature in the grinding zone, should be the smaller grinding wheel rotation speed and grinding depth, and improve the proper movement speed. Specific content as follows:

(1) Literature review of grinding machining and grinding zone temperature field heat source model in the study of the theory and method of the grinding zone heat source temperature field analysis research, and then theoretically established the mathematical model of temperature field, and confirmed the heat for form grinding plane.

(2) Finite element method and finite element analysis software ANSYS learning. Learning ANSYS thermal analysis from modeling, solving the post-processing. The late for grinding zone temperature field simulation to prepare for.

(3) Titanium alloy with ANSYS grinding plane model simulation, and change processing technology parameters and simulation and comparison analysis of simulation results concluded.
