Purpose and goal
The methodology developed in the project meets predefined aims to enhance the ability to take the early model-based design decisions. The project has strengthened the cooperation between industry and academia, and also influenced the undergraduate education at Linköping University. The project has also had connections with the EU-funded research project CRESCENDO with more than 60 partners from the European aerospace industry and academia. This has contributed to improved international relations in the field of Virtual Testing and Virtual Certification.
Results and expected effects
The project has resulted in new methodology for early validation and uncertainty analysis of simulation models. When sufficient system level measurement data for validation purposes is unavailable, this method provides a means to use knowledge of component level uncertainty for assessment of model top level uncertainty. The method is integrated in a Modelica component library and is evaluated using an industrial application example. The project has also contributed to the development of Saab Aeronautics Handbook for Development of Simulation Models.
Approach and implementation
The project was conducted in collaboration between Saab Aeronautics and the Division of Machine Design at IEI, Linköping University. The project has included an industrial PhD candidate from Saab Aeronautics, located at Linköping University. The contribution from Saab Aeronautics is primarily ensuring industrial relevance, providing methods, tools, simulation models, and evaluation of the developed methodology.
