Research on finite element modeling technique of precision forming simulation for complex precision forging part
This paper discusses the key technique of finite element modeling for complex precision forging part, which includes geometrical modeling, element type selecting, element meshing and remeshing, material model selecting, friction model definition and contact problem, In addition, the particular application of complex precision forging part in precision forming finite element modeling was shown combined with Hooke's Joint. Finally the main problems being studied subsequently of the finite element modeling for complex precision forging part were also presented.
