  1. 1. Constraint-based conceptual design using principle solution elements

    Författare :Sören Wilhelms; Christian Weber; Linköpings universitet; []
    Nyckelord :Conceptual design; functional modelling; constraint-based design; design reuse; VDI 2222; product modelling; design support; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The design of new products is an important engineering activity, and much of the competitiveness in high-salary countries depends on the ability to develop innovative products with acceptable time to market.During conceptual design, the principle solution for a product is conceived.

  3. 2. CAD-Model Parsing for Automated Design and Design Evaluation

    Författare :Roland Stolt; Staffan Sunnersjö; Ola Isaksson; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design automation; CAD; KBE; Feature based modelling; Feature recognition; Product development.; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : Product development has both innovative and analytic sides. Starting from the requirements, a design suggestion is generated. In order to assess how well the envisioned design fulfils the requirements, it is sometimes necessary to build a computer model of it for the analysis. LÄS MER

  4. 3. LES stochastic modelling of cavitation with its applications in OpenFOAM

    Författare :Boxiong Chen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rayleigh-Plesset Equation; Cavitation; Modelling; Simulation; Eulerian Stochastic Field Method; OpenFOAM; Homogeneous Equilibrium Model;

    Sammanfattning : Cavitation is a vaporization process that commonly happens in high-pressure injector nozzles nowadays. It has been shown by previous studies that cavitation has a significant influence on the subsequent atomization process, the quality of which would in turn heavily affect the process of combustion.

  5. 4. Macroscopic modelling of coupled multiphysics in swelling cellulose based materials

    Författare :Marcus Alexandersson; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiphysics; multiphase flow; mixture theory; porous media; cellulose based materials; paperboard;

    Sammanfattning : Paperboard has been the basis for packaging materials used to aseptically store and protect food and beverages for a long time. To ensure that there are no bacteria that can spoil the product, sterilizing treatments are made. LÄS MER

  7. 5. From CAD to FEA : A design automation perspective

    Författare :Roland Stolt; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Idealisation; CAD; Finite element analysis; mid-surfaces; KBES; Feature based modelling; knowledge based systems; TECHNOLOGY; TEKNIKVETENSKAP; Construction engineering; Konstruktionsteknik;

    Sammanfattning : CAD-models of parts produced by injection moulding or die-casting are often complex making the task of automated geometrical idealisation for finite element analysis difficult. Conventional tools for geometric idealisation are not ideal for the task, as will be shown in the thesis. LÄS MER
