Optimization of lifecycle robustness in early development phases II

Purpose and goal

The purpose of this project was to identify the roll of robust design and geometry assurance in early phases in development of aero engine components. Within the project a decision support system was developed to support a robust design process which was based on simulation tools. Virtual robustness analysis and quantification of uncertainties leads to an increased validity in early product development phases. This has also contributed to shortening of lead times and more reliability in the function of the products.

Expected results and effects

The methodology developed within this project contributes to an academic understanding of how to evaluate geometric variation in multidisciplinary simulations and provides a tool for industry. The project have generated the novel multidisciplinary modeling and simulation techniques that have been incorporated and demonstrated at the company involved in this research. This project has also lead to an application towards a European Aeronautics Research project with multidisciplinary optimization as a central theme.

Planned approach and implementation

The project has been focusing on modelling and simulation and strongly connected to experimental results. In a series of case studies, the methodology was tested in an industrial setting, where its capability was demonstrated through several applications. The goal with this strategy was to find a balance between detailed and simplified information in connection with other disciplines and how these would work in global product development perspective.
