  2. 1. From CAD to FEA : A design automation perspective

    Author : Roland Stolt; Jönköping University; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Simulation-driven design : Motives, Means, and Opportunities

    Author : Ulf Sellgren; KTH; []
    Keywords : CAD; CAE; FE method; Metamodel; Object model; PDM; Physical behavior; System; Mechanical engineering; 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

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

    Author : Roland Stolt; Staffan Sunnersjö; Ola Isaksson; Jönköping University; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Knowledge Based Integrated Multidisciplinary Aircraft Conceptual Design

    Author : Venkata Raghu Chaitanya Munjulury; Petter Krus; Roland Stolt; Linköpings universitet; []
    Keywords : Knowledge-base; Aircraft; Conceptual Design; CAD; XML Database; Multidisciplinary; Optimization;

    Abstract : 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.
