摘　　要：通过建立高精密数控立式静压圆台磨床的有限元模型,进行了磨床的热源分析及计算,并采用ANSYS Workbench进行了有限元温度场分析求解,得到了立式磨床的温度分布。进而搭建了机床温升实验平台,进行了卧磨头磨削平面时的机床温升实验。通过对有限元理论分析求解与实验结果对比,证明了有限元分析模型及方法的可靠性,为磨床的结构优化及误差补偿提供了依据。A finite element model （ FEM ） on high-precision CNC vertical frustum of cone grinding machine was established. Through calculation and analysis of the heat source and load of the machine, the temperature distribution of the vertical grinding ma-chine was solved with FEM analysis by using ANSYS Workbench. Then an experimental platform was built for temperature rise test of the machine, meanwhile, the experience of temperature rise was conducted on the grinding machine at the horizontal grinding head working time for a plane. Through contrast between the FEM solution with theoretic analysis and test result, it proves that the finite ele-ment analysis model and method are reliable, which provide reference for structural optimization and thermal error compensation of the grinding machine.
