   Sammanfattning : MULTIDESCIPLINARY design optimization (MDO) has developed in theory andpractice during the last three decades with the aim of optimizing complexproducts as well as cutting costs and product development time. Despite thisdevelopment, the implementation of such a method in industry is still a challenge andmany complex products suffer time and cost overruns. LÄS MER

3. 2. Metamodel-Based Design Optimization : A Multidisciplinary Approach for Automotive Structures

   Författare :Ann-Britt Ryberg; Larsgunnar Nilsson; Harald Hasselblad; Linköpings universitet; []
   Nyckelord :Metamodel-based design optimization MBDO ; multidisciplinary design optimization MDO ; automotive structures;

   Sammanfattning : Automotive companies are exposed to tough competition and therefore strive to design better products in a cheaper and faster manner. This challenge requires continuous improvements of methods and tools, and simulation models are therefore used to evaluate every possible aspect of the product. LÄS MER

4. 3. Towards Design Automation for Additive Manufacturing : A Multidisciplinary Optimization approach

   Författare :Anton Wiberg; Johan Andersson (Ölvander); Johan Persson; Lars Pejryd; Linköpings universitet; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In recent decades, the development of computer-controlled manufacturing by adding materiallayer by layer, called Additive Manufacturing (AM), has developed at a rapid pace. The technologyadds possibilities to the manufacturing of geometries that are not possible, or at leastnot economically feasible, to manufacture by more conventional manufacturing methods. LÄS MER

5. 4. Metamodel-Based Multidisciplinary Design Optimization of Automotive Structures

   Författare :Ann-Britt Ryberg; Larsgunnar Nilsson; Anirban Basudhar; Linköpings universitet; []

   Sammanfattning : Multidisciplinary design optimization (MDO) can be used in computer aided engineering (CAE) to efficiently improve and balance performance of automotive structures. However, large-scale MDO is not yet generally integrated within automotive product development due to several challenges, of which excessive computing times is the most important one. LÄS MER

7. 5. Design Automation for Multidisciplinary Optimization : A High Level CAD Template Approach

   Författare :Mehdi Tarkian; Johan Ölvander; Xiaolong Feng; Fredrik Elgh; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : In the design of complex engineering products it is essential to handle cross-couplings and synergies between subsystems. An emerging technique, which has the potential to considerably improve the design process, is multidisciplinary design optimization (MDO).MDO requires a concurrent and parametric design framework.
