This project aims to build a working design-analyze-optimize methodology for Alstom Power Sweden AB at Växjö, Sweden. In order to be profitable in today’s competitive industrial product market, it is necessary to engineer optimized products fast. This involves CAD design and FEA analysis to work within an optimization routine in a seamless fashion which will result in a more profitable product.
This approach can be understood as a model-based design, where the 3D CAD data is central to the product life cycle. The present approach provides many benefits to a company because of the use of a central database ensure access to the latest release of the 3D model. This allows for a streamlined design to fabrication life cycle with inputs from all departments of a product based company.
Alstom is looking into automating some of their design process so as to achieve efficiency within their design department. This report is the result of a study where an industrial silo is taken as an example. A design loop involving CAD design and FE analysis is built to work with an optimization routine to minimize the mass and also ensure structural stiffness and stability.
Most engineers work with a lot of constraints with regard to material stock size and other design codes (e.g. Euro Codes). In this report an efficient way to design an industrial product in a 3D CAD (CATIA) program so as to stay within these constrains and still obtain credible computation results within an optimization loop will be discussed.
