Design optimization of the tool structure for stamping an automotive part with the high strength steel

Optimum shape design of the tool structure is carried out in order to decrease the deformation and the stress from the large amount of stamping load with a simultaneous effect of weight reduction. Topology optimization is carried out to design the shape of the rib structure and Taguchi method is utilized to optimize the core shape. As a result of optimization, the weight of the rib and the core structures is reduced to 3.1% and the deformation and the stress of the rib and the core structures are decreased to 10.6% and 3.7% comparing to the initial design, respectively.
