Optimization of lifecycle robustness in early development phases

Important results from the project

This project aims at developing the capability to balance and optimize the lifecycle robustness of a product, i.e. the balance between safety requirements, technical requirements, producibility, performance as well as ecological and economic sustainability. A multidisciplinary simulation tool has been developed to balance performance requirements (aero- and thermodynamics, structural integrity and materials) are balanced with tolerance requirements, producibility, giving a nuanced overview of the entire product development process.

Expected long term effects

The project has developed a methodology that balances engineering disciplines so that the process can be optimized from a holistic perspective. A simulation platform has been developed, where product concepts can be evaluated automatically based on aerodynamics, structural integrity, geometric robustness and producibility. The project has resulted in four conference papers, one journal publication, two book chapters, and one licentiate thesis. The project will be followed by the NFFP6 project ´Optimization of lifecycle robustness II´.

Approach and implementation

The project was oriented towards modeling and simulation, and was closely tied to experimental results, both in the aspects of pure part-scale experiments which were conducted within other projects, and in the test cases, where the methodology was applied on real and conceptual products.
