| Abstract: | FEM simulations for three different kinds of Ti-1023 hub forging billets' processing had been carried out with the Auto-Forge software. The simulation results of filling mold cavities processing as well as the equivalent plastic strain, temperature distribution load curve and mold normal stress had been analyzed and discussed. Several reasons which result in the FEM calculation tolerances are also discussed. It is pointed out that we must focused the FEM simulation on the area of complex shape aerospace forg-ings' processing and its microstructure, grain size, properties prediction. |
