    Sammanfattning : This dissertation explores the complexities of regional economic restructuring. It casts a light on how regional environments are ‘reconfigured’ in relation to the transformation of existing regional industries and the development of new ones. 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. Multidisciplinary Design Optimization of Automotive Structures

    Författare :Rebecka Domeij Bäckryd; Larsgunnar Nilsson; Per-Olof Marklund; Linköpings universitet; []
    Nyckelord :Multidisciplinary design optimization MDO ; single-level optimization methods; multi-level optimization methods; metamodel-based design optimization MBDO ; automotive structures;

    Sammanfattning : Multidisciplinary design optimization (MDO) can be used as an effective tool to improve the design of automotive structures. Large-scale MDO problems typically involve several groups who must work concurrently and autonomously for reasons of efficiency. When performing MDO, a large number of designs need to be rated.

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

    Författare :Ann-Britt Ryberg; Larsgunnar Nilsson; Anirban Basudhar; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multidisciplinary design optimization MDO ; metamodel; artificial neural network ANN ; support vector machine SVM ; sequential sampling; crashworthiness; automotive structure; spot weld optimization;

    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. Prediction of structural dynamic behaviour under uncertainties: With applications to automotive structures

    Författare :Mladen Gibanica; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor localisation; experimental design; noise and vibrations; structural dynamics; automotive industry; model updating; uncertainty quantification; substructuring;

    Sammanfattning : The automotive industry is moving towards shorter development cycles for new car generations. This means that less expensive prototypes can be built and tested, and that, increasingly, computer models must be used for decision making. LÄS MER
