  1. 1. Cost Optimization of Aircraft Structures

    Detta är en avhandling från Stockholm : KTH

    Författare :Markus Kaufmann; KTH.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Sammanfattning : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. LÄS MER

  3. 3. Knowledge Based Integrated Multidisciplinary Aircraft Conceptual Design

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Venkata Raghu Chaitanya Munjulury; Linköpings universitet.; Linköpings universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knowledge-base; Aircraft; Conceptual Design; CAD; XML Database; Multidisciplinary; Optimization;

    Sammanfattning : With the ever growing complexity of aircrafts, new tools and eventually methods to use these tools are needed in aircraft conceptual design. To reduce the development cost, an enhancement in the conceptual design is needed.This thesis presents a knowledge-based aircraft geometry design tool RAPID and the methodology applied in realizing the design.

  4. 4. Collaborative Multidisciplinary Design Optimization A Framework Applied on Aircraft Systems and Industrial Robots

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Edris Safavi; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In a product development process, it is crucial to understand and evaluate multiple and synergic aspects of systems such as performance, cost, reliability and safety. In order to improve the foundations for decision-making, this thesis presents methods that are intended to increase the engineering knowledge in the early design phases. LÄS MER

  5. 5. Metamodel-Based Design Optimization A Multidisciplinary Approach for Automotive Structures

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Ann-Britt Ryberg; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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
