Abstract:Cost saving and product improvement have always been important goals in the metal
forming industry. To achieve these goals, metal forming processes need to be optimised. During
the last decades, simulation software based on the Finite Element Method (FEM) has significantly
contributed to designing feasible processes more easily. More recently, the possibility of
coupling FEM to mathematical optimisation algorithms is offering a very promising opportunity
to design optimal metal forming processes instead of only feasible ones. However, which
optimisation algorithm to use is still not clear.
In this paper, an optimisation algorithm based on metamodelling techniques is proposed
for optimising metal forming processes. The algorithm incorporates nonlinear FEM simulations
which can be very time consuming to execute. As an illustration of its capabilities, the
proposed algorithm is applied to optimise the internal pressure and axial feeding load paths
of a hydroforming process. The product formed by the optimised process outperforms products
produced by other, arbitrarily selected load paths. These results indicate the high potential of
the proposed algorithm for optimising metal forming processes using time consuming FEM
simulations.
