Generative Design Approach for Modelling of Large Design Spaces

Abstract

Mass customisation of mechanical and mechatronic products requires computer-aided configuration tools including parametric models of the product. For an extended individual adaption, approaches including iterative configuration processes are necessary. Knowledge-based engineering systems (KBES) are developed for this kind of customisation tasks among other things, but they are still not universally applicable and accepted in the industry. Thus, in this paper, an approach for the modelling of large design spaces by parametric models is presented. This approach implies a confinement of the widely defined pretension of KBES by a systematic modelling of practical conversant design solutions. In contrast to the modelling of higher-level design rules, the exclusion of inexpedient variants is completely possible. The detailed aspects of the approach consisting of a structural design, effective areas and design elements are illustrated in this paper as well as methodological aspects. The application is demonstrated by a wheel carrier design.
