摘 要：A reasonable finite element (FE) model of grinding temperature field has been developed on the basis of analysis of transient temperature field. And three kinds of boundary conditions are loaded on the element of a moving heat source. The study, which is based on the finite element principle, has been carried out using the numerical simulation software ANSYS. Many results have been obtained including three dimensional temperature distribution map. The simulated results under different conditions show good agreement with experimental results. The temperature of the dry-grinding has been compared with that of the wet-grinding. It shows that the wet-grinding highly decrease the temperature of the workpiece. Finally, the variable coefficient of convective heat transfer and the different trapeziform heat source have been discussed in this paper.
