Topological Optimization in Mechanical Constructions—An Example of Application

Abstract

The article will refer to an example of topological optimization applied to a typical constructional form of an exemplary technical object. Topological optimization, in this case, is to reduce the mass of the element by removing the material that is not necessary to fulfil its objective function, resulting from specific design requirements and accepted criteria. The object form resulting from topological optimization is usually theoretical and presents only the optimal distribution of material in the design space. The development of the target construction form requires further modelling activities. The presented topological optimization process was made using the Altair Inspire [1] system. While, the CATIA v5 [6] system was used for further modelling. Target constructions will be made taking into account two manufacturing technologies: (1) cutting from sheet metal, bending, and welding, and (2) generative technology (DMLS) [8]. All obtained functional models of the same object will be compared in terms of strength characteristics and the obtained weight loss.
