  3. 17. Technical cost modelling and efficient design of lightweight composites in structural applications

    Författare :Mathilda Karlsson Hagnell; Malin Åkermo; Dan Zenkert; Gerhard Ziegmann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technical cost modelling; composite materials; carbon fibre; lightweight design; optimization; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : A lightweight transport design reduces fuel costs and emissions and can be achieved through the use of fibre-reinforced composite materials. Although lightweight, the composite raw material can be expensive and the sequential component production challenging and costly. LÄS MER

  4. 18. Analysis of the Unsteady Flow Field of a Passenger Vehicle

    Författare :Lennert Sterken; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind tunnel; Wake; CFD; Pressure measurements; Extensions; Yaw response; External aerodynamics; Aerodynamic forces;

    Sammanfattning : Political legislation and consumer requirements for a sustainable society require that vehicle manufacturers focus on reduced fuel consumption and lower emissions. Areduction in the overall energy consumption can be directly linked to a decrease of the driving resistance, where the aerodynamic drag significantly contributes at velocities above 70km/h. LÄS MER

  5. 19. Vision based perception systems for unmanned forestry machines

    Författare :Songyu Li; Magnus Karlberg; Håkan Lideskog; Torbjörn Lindbäck; Tomas Nordfjell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Sammanfattning : After years of continuous development in the past decades, the field of forest production has achieved a notable degree of mechanization. Nonetheless, the unceasing demand for increased productivity in forestry operations continues to drive the rapid expansion of forestry automation. LÄS MER

  7. 20. Fatigue and Fracture of High-Strength Steels : Improving Reliability in Strength Assessment

    Författare :Gustav Hultgren; Zuheir Barsoum; Rami Mansour; Torbjörn Narström; Gary Marquis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-Strength Steel; Quality assurance; Probabilistic modeling; Fatigue; Fracture mechanics; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Structural steel plays a fundamental role in the heavy industry, serving as a key material for numerous load-bearing products and equipment. Its widespread use is attributed to its robustness, resistance to wear, ease of use in construction, and cost-effectiveness. LÄS MER
