  1. 11. Logistics of Earthmoving Operations : Simulation and Optimization

    Författare :Jiali Fu; Haris Koutsopoulos; Andreas Tapani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Earthworks are a fundamental part of heavy construction engineering and involve the moving and processing of the soil surface of earth. Normally, earthmoving operations are carried out during the early stages of heavy construction projects. LÄS MER

  3. 12. Simulation-driven design : Motives, Means, and Opportunities

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

    Sammanfattning : 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”. LÄS MER

  4. 13. Production simulation as a management tool

    Författare :Torbjörn Ilar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : This thesis focuses on process simulation and modelling in the context of production engineering. The thesis is presented in the form of seven papers which range in content from the holistic analysis of the application of modelling (papers 1-5) to a detailed examination of some of the areas of weaknesses in commercially available software (papers 6 and 7).

  5. 14. Regenerative Chatter Vibration in Indexable Drills : Modeling and Simulation

    Författare :Amir Parsian; Tomas Beno; Mahdi Eynian; Martin Magnevall; Erhan Budak; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound; Vibrations; Drill; Indexable; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : An indexable insert drill is a drill which uses cutting inserts to make holes. Undesirable sound generated by this type of drill has always been considered as a problem in workshops. The focus of this thesis is to investigate the mechanism behind these vibrations, to model it and to provide guidelines for reducing the sound in future drill designs. LÄS MER

  7. 15. Compression moulding of SMC : experiments and simulation

    Författare :Jimmy Olsson; Daniel Ståhlberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Due to excellent properties and relatively low material and manufacturing costs, the use of fibre reinforced polymer composites have increased during the last decades. One method that is suitable for large scale productions of e.g. lightweight vehicle components is compression moulding of sheet moulding compound (SMC). LÄS MER
