  1. 1. Advancing the life cycle energy optimisation methodology

    Författare :Hamza Bouchouireb; Ciarán J. O'Reilly; Peter Göransson; Rupert J. Baumgartner; José Potting; Tracy Bhamra; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; HUMANITIES; HUMANIORA; TEKNIK OCH TEKNOLOGIER; HUMANIORA; ENGINEERING AND TECHNOLOGY; HUMANITIES; life cycle energy; vehicle design; optimisation; functional conflicts; livscykelenergi; fordonsdesign; optimering; tvär-funktionella konflikter; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : The Life Cycle Energy Optimisation (LCEO) methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle, while complying with a set of functional constraints. This effectively balances trade-offs, and therewith avoids sub-optimal shifting between the energy demand for the cradle-to-production of materials, operation of the vehicle, and end-of-life phases.

  2. 2. On Derailment-Worthiness in Rail Vehicle Design : Analysis of vehicle features influencing derailment processes and consequences

    Författare :Dan Brabie; Evert Andersson; Roderick A Smith; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; derailment; bogie design; wheel-sleeper impact; simulation; deviation; vehicle inter-connection; guidance mechanism; substitute guidance; articulated train; railway safety; Vehicle engineering; Farkostteknik;

    Sammanfattning : This thesis aims at systematically studying the possibilities of minimizing devastating consequences of high-speed rail vehicle derailments by appropriate measures and features in the train design including the running gear. Firstly, an empirical database is established containing as much relevant information as possible of past incidents and accidents that have occurred at substantial running speeds due to mechanical failure close to the interface between the running gear and the track.

  3. 3. Suspension design for off-road construction machines

    Författare :Adam Rehnberg; Lars Drugge; Annika Stensson Trigell; David Crolla; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction machine; engineering vehicle; earth mover; wheel loader; vehicle dynamics; vehicle engineering; whole body vibrations; off-road vehicle; anläggningsmaskin; entreprenadmaskin; hjullastare; fordonsdynamik; fordonsteknik; helkroppsvibrationer; terrängfordon; Vehicle engineering; Farkostteknik;

    Sammanfattning : Construction machines, also referred to as engineering vehicles or earth movers, are used in a variety of tasks related to infrastructure development and material handling. While modern construction machines represent a high level of sophistication in several areas, their suspension systems are generally rudimentary or even nonexistent. LÄS MER

  4. 4. Multidisciplinary Design in Aeronautics, Enhanced by Simulation-Experiment Synergy

    Författare :Tomas Melin; Arthur Rizzi; Jesper Oppelstrup; Ray Whitford; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeronautics; conceptual design; design; high lift systems; Vehicle engineering; Farkostteknik;

    Sammanfattning : This thesis covers some aspects of current aircraft design, and presents how experiment and simulation are used as tools. Together they give enhanced effects over employing either one separately. The work presented has been produced using both simulations and experiments. LÄS MER

  5. 5. Driver-Vehicle Interaction : Identification, Characterization and Modelling of Path Tracking Skill

    Författare :Andreas Erséus; Stensson Trigell Annika; David Cole; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik; Psychology; Psykologi;

    Sammanfattning : Since the dawn of the automobile, driver behaviour has been an issue. Driving can result in accidents that may harm not only the driver but also passengers and the surroundings. This calls for measures that restrict the usage of vehicles and to assist the individual driver to conduct the driving in a safe, yet practically efficient manner. LÄS MER
