  2. 21. Design Automation Systems for Production Preparation : Applied on the Rotary Draw Bending Process

    Author : Joel Johansson; Staffan Sunnersjö; Bo Bengtsson; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design automation; Rotary draw bending; Knowledge Based Engineering KBE ; and Finite Element Analysis FEA ; Other technology; Övriga teknikvetenskaper;

    Abstract : Intensive competition on the global market puts great pressure on manufacturing companies to develop and produce products that meet requirements from customers and investors. One key factor in meeting these requirements is the efficiency of the product development and the production preparation process. READ MORE

  4. 22. Integrated design systems supporting thermal-structural analysis in product development

    Author : Peter Eliasson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : This work covers integrated computer-aided applications for design and analysis in particular different integrated design systems for thermal and structural simulations. Two different design systems have been integrated to improve efficiency in product development, i.e. reduced lead-time and higher quality of the product. READ MORE

  5. 23. Fatigue assessment of complex welded steel structures

    Author : Johan Martinsson; Jack Samuelsson; Wolfgang Fricke; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Abstract : To improve the usage of material in fatigue loaded complex welded structures a better calculation method (based on FEA) is needed than what is available on the market and an improved management of weld quality. Improved FE-procedures are directly applicable to design of generic structural components within virtually all industries using CAD and FEtools, irrespective of industrial sector. READ MORE

  6. 24. Experimental and analytical study of thermal mixing at reactor conditions

    Author : Mattia Bergagio; Henryk Anglart; Horst-Michael Prasser; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-cycle thermal fatigue; Hilbert-Huang transform; large eddy; WALE; rainflow; inverse heat conduction; adjoint conjugate gradient; Energy Technology; Energiteknik; Fysik; Physics;

    Abstract : High-cycle thermal fatigue due to turbulent mixing of streams at distinct temperatures is an interdisciplinary issue affecting safety and life extension of existing reactors together with the design of new reactors. It is challenging to model damage and thermal loads arising from the above mixing. READ MORE

  7. 25. Finite Element Analysis and Design of Experiments in Engineering Design

    Author : Martin Eriksson; Innovation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element analyses; Predictive Design Analysis; Mechanical engineering design process; Design Of Experiments; Predictive Engineering;

    Abstract : Projects with the objective of introducing Finite Element Analysis (FEA) into the early phases of the design process have previously been carried out at the Department of Machine Design, see e.g. the Doctoral thesis by Burman [13]. These works clearly highlight the usefulness of introducing design analysis early in the design process. READ MORE
