  1. 21. On Structural Design of High-Speed Craft

    Författare :Mikael Razola; Jakob Kuttenkeuler; Anders Rosén; Olav Fredrik Rognebakke; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slamming; high-speed craft; finite-element analysis; design methods; experimental analysis; numerical simulations; design loads; statistical analysis;

    Sammanfattning : The development in structural design and construction of high-speed craft has been extensive during the last decades. Environmental and economical issues have increased the need to develop more optimized structures, using new material concepts, to reduce weight and increase performance efficiency. LÄS MER

  3. 22. Distributed vehicle testing : dynamic simulation for automotive winter testing

    Författare :Mikael Nybacka; Luleå University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Today, rather than provide parts similar to their competitors and rely on one or two automakers, successful automotive component suppliers focus heavily on innovation and collaboration with several manufacturers in a global market. In this thesis, an as-is scenario for automotive winter testing is presented. LÄS MER

  4. 23. On the ECO2 multifunctional design paradigm and tools for acoustic tailoring

    Författare :Juan Pablo Parra Martinez; Peter Göransson; Olivier Dazel; Jacques Cuenca; Per Wennhage; Franck Sgard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle design; planned obsolescence; anisotropy; porous materials; sound absorbing materials; acoustic modelling; power balance; energy assessment; dissipated power.; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Nowadays vehicle design paradigm influences not only the effectiveness of the different means of transport, but also the environment and economy in a critical way. The assessment of the consequences that design choices have on society at large are necessary to understand the limits of the methods and techniques currently employed. LÄS MER

  5. 24. Light-weighting Methodology in Rail Vehicle Design through Introduction of Load Carrying Sandwich Panels

    Författare :David Wennberg; Sebastian Stichel; Per Wennhage; Ragnar Larsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sandwich panels; rail vehicle; lightweight; optimisation; carbody; Vehicle engineering; Farkostteknik; Construction engineering; Konstruktionsteknik; Construction materials; Konstruktionsmaterial;

    Sammanfattning : Lightweight design in rail vehicles has been important for quite some time. Structures have been optimised to fulfill their purpose and cut unnecessary weight to reach allowable axle loads. Classically this is done by using steel, thin-walled structures, throughout the car body, or, alternatively, power-pressed aluminum profiles. LÄS MER

  7. 25. Demystifying the Black Box - Exploring How Users Make Sense of Fully Automated Vehicles

    Författare :Mikael Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Automated vehicles; Driving Automation; Meaning; Conceptual model; Make sense; Product semantics; Signifiers; Understanding;

    Sammanfattning : Vehicles are becoming increasingly automated. Already today vehicles are able to take over and assist the human driver in certain driving tasks, and the scope of technical possibilities is rapidly expanding. However, for the proliferation of AVs to occur, there are several challenges that must first be overcome. LÄS MER
