摘　　要：磨削温度作为影响磨削淬硬工艺的重要因素,直接关系着工件的表面质量。为研究其在磨削淬硬过程的分布情况,确定磨削淬硬机理,建立磨削温度场的数学模型,并采用ANSYS软件对其进行有限元仿真研究,通过对磨削温度场的分布以及变化情况的分析验证磨削淬硬的机理,并根据仿真结果对淬硬层深度进行预测。最后进行磨削淬硬试验,对工件显微硬度进行测量,将预测结果和试验结果进行比较,验证仿真结果的有效性,表明可以通过仿真来对其进行研究。Grinding temperature which is the most important factor of the grind-hardening technology affects the surface quality of the workpiece directly. In order to study the temperature distribution and the mechanism of the technology, the mathematical model of the grinding temperature field was established, and the FEA simulation was conducted by using ANSYS software, and the mechanism of grind-hardening was proved through the analysis of the distribution and changing of the grinding temperature field, and then the hardened depth was predicted with the simulation result. At last, the grinding experiment was carried out, and the prediction result was proved consistent with the analysis of the hardness distribution of the workpiece, which indicates that the simulation results are available and feasible to study ~rind-hardenin~ by means of FEA simulation.
