摘　　要：针对涡轮叶片在铣削加工中的变形问题,基于SolidWorks和ABAQUS软件,建立了某涡轮叶片的三维模型,进行了铣削变形有限元仿真分析,获得了涡轮叶片变形的基本规律。针对涡轮叶片加工变形过大不能满足精度要求的问题,改进装夹方式,改进后的仿真结果表明方案可行。用三维扫描仪扫描零件并生成实际工件的模型,与理论模型对比。结果表明:有限元分析得出的变形量及其变形位置和趋势与实际工况条件下加工出的零件变形分布区域及趋势相符,证明铣削力模型的正确性以及利用有限元方式分析叶片加工过程的可行性,为进一步研究叶片多轴加工变形控制提供了思路。A finite element analysis model of the turbine blade was built based on SolidWorks and ABAQUS software due to the deformation in the milling of the turbine blade. According to the finite element simulation analysis of the milling deformation, the basic law of the turbine blade deformation was obtained. Meanwhile, in allusion to the too large milling deformation of turbine blade which can not satisfy the accuracy requirement, the clamp methods were changed, and the improved simulation results show that the scheme is feasible. The part was scanned by the three- dimensional scanner to generate the model of the actual workpiece, which was compared with the theoretical model. The results show that the model formula of the milling force and milling deformation finite element simulation can be considered reliable, and this also provides an idea for further research on blade deformation control of multi-axis machining.
