Abstract:
Within the Collaborative Research Centre SFB/TRR 30 a stub shaft is produced by applying the highly innovative metal forming technology of the simultaneous hot and cold forging in combination with a hardening process performed directly in the closed forging dies after the forging step. This complex forging process is completely simulated with the finite element code LS-DYNA including the local inductive heating phase of the workpiece as well as the rapid cooling process under pressure of the final stub shaft inside the forging dies. A new meshless element formulation denoted as element-free Galerkin method (EFG) is successfully applied to the forging process in addition to the simulation with standard finite elements. The process of the inductive heating is modelled in a simplified way. The simulation results are validated by means of experimentally measured data, showing good agreement.
