  1. 1. Dynamics of Vehicle-Deck Interactions

    Författare :Junbo Jia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle-deck interactions; Lightweight structure; Vehicle dynamics; Vibration analysis.; Lashing; Vehicle securing; Ship motions; Modal testing; Finite element analysis;

    Sammanfattning : The work presented in this thesis concerns the modelling and analysis of vehicle-ship deck interactions. The physical modelling of vehicles is discussed together with the modelling of supporting structures/ship decks, and the interactions between vehicles and supporting structures. LÄS MER

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

    Författare :Adam Rehnberg; Lars Drugge; Annika Stensson Trigell; David Crolla; KTH; []
    Nyckelord :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. 3. Driver-Vehicle Interaction : Identification, Characterization and Modelling of Path Tracking Skill

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

  5. 4. 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 :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.

  7. 5. Towards sustainable urban transportation : Test, demonstration and development of fuel cell and hybrid-electric buses

    Författare :Anders Folkesson; Per Alvfors; Peter Treffinger; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acceptance; analysis; auxiliary system; bus; Clean Urban Transport for Europe; concept; CUTE; demonstration; driver; drive cycle; duty cycle; energy flow; evaluation; fuel cell; heavy duty vehicle; hybrid management; hybrid vehicle; hydrogen; passenger; PEM; safety; Sankey diagram; series hybrid; sustainable; test; urban transport; vehicle simulation; acceptans; analys; hjälpaggregat; buss; Clean Urban Transport for Europe; koncept; CUTE; demonstration; körcykel; förare; energiflöde; utvärdering; bränslecell; tunga fordon; hybridsystemkontroll; hybridfordon; vätgas; passagerare; PEM; säkerhet; Sankey-diagram; seriehybrid; uthållig; hållbar; test; stadstransport; fordonssimulering; Vehicle engineering; Farkostteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. LÄS MER
