平面磨削温度场有限元仿真及实验

FEM Simulations and Experimental Study on the Temperature Field in Surface Grinding

在考虑不同磨削参数对温度场的影响的情况下,根据三角形热源模型对磨削工件进行了有限元仿真,获得了工件的温度分布。采用热电偶法测量了工件的磨削温度,发现有限元仿真值与实验测量值相当吻合,仿真结果能够真实反映工件的温度场。该有限元仿真方法对磨削过程中工件温度场的研究具有实际意义,为避免磨削烧伤提供了技术支持。

Different grinding parameters influenced upon temperature field are considered in this paper. FEM simulations are carried out for workpieces by using the triangle heat source model,and the distribution of temperature field is obtained easily. The grinding temperatures are measured by thermocouple method and compared with the simulation results. A good agreement is found between FEM results and experimental measured temperatures,which means the FEM simulation results could show the real thermal conditions of workpieces. The study has great meaning for the temperature field of workpieces in grinding process,which provides technical support to avoid grinding burn.
