摘要
基于有限元数值方法建立了RAW200/160-5型径轴向轧环机轧制某航空发动机涡轮机匣环形锻件的三维仿真模型,对成形过程进行了虚拟轧制,计算结果与实际生产过程非常吻合,结果还显示了环件轧制实时扩展的过程。
A three dimensional numerical mod- el of the RAW200/160-5 radial axial ring rolling machine is built based on the finite element method, and then the entire virtual rolling process of a turbine case blank is realized. The simulation results that it keeps good agreement with the practical deforming process, and the real-time expanding of ring is also given out.
