Grinding is the important processing in machine manufacture, the technology of grinding holds the extremely important position in the machine manufacture, the characteristics and the superiority of abrasive machining which is in sole possession of by it widely applies in various departments and so on astronautics, aviation. Among them, grinding thermal reaction has enormous influence on the work piece quality of surface and operational performance, and can affect the service life of the grinding wheel. Therefore, it has become an important research topic for researchers to study the temperature field in grinding area.In the paper, it has introduced to the research achievement of the field domestically and abroad, and made theoretically analysis to temperature computation of grinding area causes by the different heat source, and to production of grinding hot in the grinding process. Then we briefly explained the application of finite element in thermal analysis. Finally taken surface grinding as the example, carry on the simulation and analysis to the temperature field of grinding area by ANSYS software .Main contents of the paper are summarized as following:(1)This thesis has simply introduced the grinding and the form of heat source in grinding area, and conducted the analysis and research with the method of heat source to the temperature field of the grinding area, then established the mathematical model of the temperature field caused by the different heat source. Finally, we have determined the form of heat source in surface grinding situation.(2)This thesis has also introduced the application of Finite Element in temperature field and simply introduced the function and main step of thermal analysis of finite element analysis software ANSYS.(3)This thesis has also established the geometry model of temperature field in surface grinding area , meshing and defines the boundary conditions by ANSYS, Finally we have realized the moving of the heat source by ANSYS Parameterization Design Language (APDL).Then we have carried the simulation on the model, and obtained distributed condition of the temperature field and acquired influence which various grinding parameter to the temperature field of grinding area.(4) Finally, the thesis has drawn some conclusion according to the result of simulation and made some forecasts to the task of the later period and pointed out some problems in the process, and given some suggestion for the next research.Finally, the paper has drawn some conclusion from the above analysis, pointed out some problems in the process, and given some suggestion for the next research.
