Collaborative Multidisciplinary Design Optimization: A Framework Applied on Aircraft Systems and Industrial Robots
Linköping University, Department of Management and Engineering, Machine Design. Linköping University, The Institute of Technology.
2013 (English)Licentiate thesis, comprehensive summary (Other academic)
Abstract [en]

In a product development process, it is crucial to understand and evaluate multiple and synergic aspects of systems such as performance, cost, reliability and safety. In order to improve the foundations for decision-making, this thesis presents methods that are intended to increase the engineering knowledge in the early design phases.

In complex products, different systems from a multitude of engineering disciplines have to work tightly together. Collaborative design is defined as a process where a product is designed through the collective and joint efforts of domain experts. Thus, a Collaborative Multidisciplinary Design Optimization (CMDO) process is proposed in the conceptual design phase in order to increase the likelihood of more accurate decisions being taken early on.

To enable higher fidelity based CMDO, it is necessary to validate the tools and models utilized. This can be done with so-called low cost demonstrators. The physical demonstrators increase the engineer’s confidence regarding the final product by validating the models as well as revealing many unknowns and thus further increasing the engineering knowledge.

The performance of the presented methods is demonstrated with two industrial applications, aircraft conceptual system design and industrial robot design.

Abstract [en]

Advances in recent years has brought forth many feasible technologies which oer signif-icant design advantages over the traditional aircraft vehicle ight systems. These advanceshave brought about a need for the aircraft conceptual engineers to evaluate these newtechnologies so as to realize a realistic and optimized architecture which fulls all criti-cal disciplinary requirements. To evaluate these systems, it is necessary to use models ofcomplexity which are a degree higher than what is being used today. Quick developmentand evaluation of these models can be a hard task for an engineer to achieve consideringthe multidisciplinary nature of the systems. A collaborative eort in model developmentbetween various department is needed if the conceptual design is to be completed withinthe time frame. To facilitate a collaborative conceptual design a research project was for-malized at Linkoping university, which has led to the development of a tool named CAVE(Conceptual Aircraft Vehicle Engineering) which can be used to evaluate the architectureof aircraft systems. In this paper, CAVE as a conceptual design tool will be presented.

Abstract [en]

An aircraft is a multifaceted product which requires cooperation between different engineering domains. Therefore, design of an aircraft is essentially a multidisciplinary activity with necessity of integrating dierent design tools to get an optimized product. At Linkoping University, a design framework is being developed to assist in the evaluation and optimization of various aircraft vehicle system architectures with the help of integrating a geometric, aerodynamic and dynamic models early in the conceptual design phase. This framework helps to identify a preliminary system concept for an energy optimized aircraft architecture with the focus on more electrical aircraft. As a case study the performance and geometrical aspects of an EMA (Electromechanical actuator) are evaluated and optimized.

Abstract [en]

When conducting design on novel mechatronic products, it can be valuable to test and evaluate the performance and properties of the concepts throughout the design process by producing them as downscaled prototypes, see Jouannet et al. [1]. This is especially true when the product is of unconventional design and the designer can get increased confidence of the proposed concept by testing it as a sub scaled version. Nonetheless, the process of realization of new concept should be done in a rapid fashion in order not to halt the design process and simultaneously increasing explicit knowledge about the concept. A case study will be illustrated which demonstrates how fully automated design and construction of downscaled prototypes is performed.
