“…As such, we leveraged existing know-how and saw a clear path from the qualitative approach towards a quantitative measure that we could implement with stiffened panels. Measuring design complexity is an ongoing area of research, with perspectives from many different disciplines (Min, Suh, & Hölttä-Otto 2015; Mohebbi, Achiche, & Baron 2018; Sinha, Suh, & de Weck 2018; Chouinard, Achiche, & Baron 2019; Bjarklev et al 2020). In this work, we focus on the definitions used in axiomatic design for conceptual design.…”

Topology optimization has been identified as a powerful tool to improve aircraft structures for many years. Yet, innovative layouts have not been successfully implemented in commercial aircraft for several reasons. One reason identified by our research group is the lack of design constraints during topology optimization, such as buckling stability, which yields complex solutions that are not easily manufacturable. Second, the complexity of the resulting layouts makes integration with other systems highly challenging. With respect to these challenges, we propose a new heuristic layout optimization process: complexity-driven layout exploration for aircraft structures (CD-LEAS). The new process addresses the challenges of complexity and nonlinear constraints, such as buckling, in aircraft structure layout optimization. The novelty of CD-LEAS comes from the integration of a relative complexity metric as a driver to navigate the design space efficiently. Two case studies of commonly used stiffened panels are carried out to showcase the performance of the process. The results show that using complexity to navigate an explicit design space allows our process to quickly output a family of simple, light, stiff and buckling-resistant layouts.

“…These graphs are easily expandable as the product development progresses (Giordano, Samper & Petit 2007) and can form the basis for tolerance analysis (Franciosa et al 2013) and synthesis (Ballu et al 2006). To further link tolerance information with other nongeometric information, such as functional requirements, and thus ensure better traceability, the Unified Modelling Language (UML) is used in numerous approaches, such as Malmiry et al (2016) and Bjarklev et al (2020). However, since UML is neither directly computer-readable nor interpretable, the Web Ontology Language (OWL) with its rigorous logic-based semantics is preferred .…”

Integrated approach enabling robust and tolerance design in product concept development

et al. 2021

Along with the ever-increasing customer demands, early consideration of variation in terms of robust design is important to avoid expensive iterations in the product development. However, existing methods are detached from the development process and can therefore only be applied at a late stage or only with comprehensive expert knowledge. Especially in the concept stage, where the geometry of a product is not yet defined and the optimisation potential is high, effective solution proposals for systematic consideration of variation are lacking. Therefore, this paper describes a new integrated approach facilitating robust and tolerance design in the concept stage. The novelty of the approach using ontologies and graph-based visualisation is the close linkage of product development and tolerance knowledge, which allows automation and helps to avoid time- and cost-intensive iteration loops. As a result, a robust and tolerance-compliant concept design, an initial qualitative tolerance specification and instructions for the further tolerancing process are already available at the end of the concept stage. The applicability and the benefits of the approach are illustrated by representative case studies and a user study allowing a critical comparison between the conventional, mostly subjective procedure and the presented approach.
