| 摘 要： | 在用热电偶进行磨削温度实验的基础上,分别运用解析法和有限元仿真法研究了金属材料超高速磨削的温度场,得出了其磨削温度场的分布；并分析了不同热源模型对温度场分布的影响.分析结果表明:随着Peclet数L值增大,磨削区热流分布从三角形变为均匀分布,且不同热源模型最高磨削温度相近,但出现的位置不同.

| Abstract: | Based on grinding temperature experiments with thermocouple,grinding temperature field in high speed grinding of the metal materials was studied by using finite element method and analytical method.The grinding temperature field caused by two heat source models were analyzed.The analysis results show that with the Peclet number L value increases,grinding heat flow in grinding zone changes from the triangle heat into a uniform heat.The maximum grinding temperatures with the two heat source models are similar,but appear in different positions in the grinding zone. |
