Numerical Simulation on Upsetting Process of Large Forgings

Abstract:

The numerical simulation on upsetting process of large forgings is conducted by using ANSYS/LS-DYNA. The FEM model is established by determining materials, contacts, constraints and loads. The distributions of strain and stress are calculated and discussed. Drum shape coefficient is defined to measure the nonuniform in deformation. The simulative values of upsetting forces are compared with those in theoretical methods, which gives the same change tendency and consistency. Influences of height-diameter ratio to strain, drum shape, tangential stress and upsetting force are also investigated, which provides basic guidance to determine process parameters in upsetting.
