The Finite Element Simulation of the Stamping Die Optimal Topology

Abstract

The problem associated with the development of specialized equipment for the production of sheet elements of aircraft structures is considered, taking into account the use of layer-by-layer growth capabilities, optimization of the rig die using finite element analysis. Finite element modeling of the tooling used as a tool for sheet stamping was carried out. In the work it is proposed to use as a tooling a model of plastic material obtained by layer-by-layer growing. As a structure of rigging, various grid structures were considered, an estimation of the strong properties of this structure was made under the conditions of the impact of the load from the press. In addition, a comparative analysis of models of optimized snap-ins constructed by layer-by-layer growth of the grid structure and topological optimization due to material redistribution, based on loading conditions. Analysis of the stress-strain state of the stamp is carried out.
