Method, system, device for topology optimization, and topology optimized component

Abstract

A computer-implemented method for improving the topology of a component includes: providing a component load case including boundary conditions for the component; providing a starting component design; and segmenting the component design into unit cells. To obtain a component design with optimal topology, the method further includes generating a surrogate model that relates possible unit cell stiffness tensors and a unit cell average density to each other. For a given unit cell average density, variations of the unit cell stiffness tensor are parameterized by the surrogate model. The method further includes using the surrogate model for improving or optimizing at least one specific unit cell parameter for each unit cell towards an optimization target; and changing the component design by amending a material mass distribution according to optimizing results.
