Unconventional Design of the Mechanical Crank Press Developed by the Topology Optimization

Popis výsledku v původním jazyce

This article deals with the design optimization of the mechanical crank press. These presses have not any significant development changes in a long time. Mechanical press LDC 250 with nominal force 2.5 MN (250 tons) was considered as an example. This type of press can be used for operations such as bending, drawing or cutting. The topology optimization was used during this research. This papers show advantage of this design method. The optimized press has lower maximal Von-Mises stress in the structure and the maximal displacement is up to two times lower. The research was focused on the main frame (open frame with shape “C”) of the press. The resistivity agaings vibrations was improved. The weight of the frame was not changed. The CAE tool NX Nastran and the optimization tool Frustum were used here. The workflow of the topological optimization is deeply described here. The comparison between the conventional (initial) and optimized design shows new approach to these machines.
