  1. 6. 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

  3. 7. Aircraft Trajectory Optimization with Tactical Constraints

    Författare :Martin Norsell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; trajectory optimization; radar cross section; stealth; radar range constraints; network centric warfare; tactical constraints; multidisciplinary optimization;

    Sammanfattning : Aircrafttrajectory optimization is traditionally used forminimizing fuel consumption or time when going from one flightstate to another. This thesis presents a possible approach toincorporate tactical constraints in aircraft trajectoryoptimization. The stealth technology of today focuses on making thetactics already in use more effective. LÄS MER

  4. 8. Optimization of Unmanned Aerial Vehicles : Expanding the Multidisciplinary Capabilities

    Författare :Athanasios Papageorgiou; Johan Ölvander; Mehdi Tarkian; Kristian Amadori; Mikael Thellner; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Over the last decade, Unmanned Aerial Vehicles (UAVs) have experienced an accelerated growth, and nowadays they are being deployed in a variety of missions that have traditionally been covered by manned aircraft. This unprecedented market expansion has created new and unforeseen challenges for the manufacturing industry which is now called to further reduce the idea-to-market times while simultaneously delivering designs of even higher performance.

  5. 9. 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. 10. 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.
