    Abstract : 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. READ MORE

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

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Ann-Britt Ryberg; Linköpings universitet.; Linköpings universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metamodel-based design optimization MBDO ; multidisciplinary design optimization MDO ; automotive structures;

    Abstract : 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. READ MORE

  4. 4. A methodology for situated and effective design of haptic devices

    University dissertation from KTH Royal Institute of Technology

    Author : Xuan Sun; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design optimization; haptic devices; metamodel; multi-criteria; situatedness; Machine Design; Maskinkonstruktion;

    Abstract : The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device. The quality of perception depends on the design of the haptic device, which presents a complex design task due to the multi-criteria and conflicting character of the functional and performance requirements.

  5. 5. Simulation-driven design Motives, Means, and Opportunities

    University dissertation from Stockholm : KTH

    Author : Ulf Sellgren; KTH.; [1999]
    Keywords : CAD; CAE; FE method; Metamodel; Object model; PDM; Physical behavior; System; TECHNOLOGY Other technology Mechanical engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Maskinteknik;

    Abstract : Efficiency and innovative problem solving are contradictory requirements for productdevelopment (PD), and both requirements must be satisfied in companies that strive to remainor to become competitive. Efficiency is strongly related to ”doing things right”, whereasinnovative problem solving and creativity is focused on ”doing the right things”. READ MORE
