Design Optimisation

As part of AMOS, a multidisciplinary design optimisation framework will be developed. This system will integrate information from the various direct energy deposisiton (DED) sytems being investigated in AMOS, the simulations which have been developed and failure models. The aim is to assess the repair and remanufacturing potential offered by DED systems and to match design decisions with maintenance options. The system will assess the economic benefits of the different repair strategies and will allow components to be redesigned based on typical damage and repair options to achieve better performance and a longer service life.

GKN are leading this work on the European side. They develop aircraft engine components for a majority of the commercial aircraft currently in service. GKN needs to develop scalable methods that can support designers to quickly optmise a given component in terms of configuration, material selection, producibility and cost within the limits of approved product methods. GKN have started to build an engineering environment with a common geometry definition. Automated geometry generation makes it possible to quickly and parametric create hundreds of models, which in turn generate computational models for several types of analysis - mechanical , aerodynamic , tolerance analysis, manufacturing simulation , and cost. The results can then used to generate response surfaces for the characteristics to be optimized. The ambition for GKN in this project will be to explore the possibility of using AM as a means to remanufacture a design based on changes in requirements.
