  2. 1. Occupant casualties in bus and coach traffic : injury and crash mechanisms

    Author : Pontus Albertsson; Ulf Björnstig; Torbjörn Falkmer; Claes Tingvall; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; bus; coach; aerodynamics; crash; non-crash; cross-wind; injuries; weight distribution; road friction; restraints; haddons matrix; prevention; severe crash; mass casualty; major incident; alighting; boarding; incidents; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : Background: The relevance of conducting this thesis is evident by the fact that bus and coach casualties have been “stubbornly stable” in Europe recent years and a need for investigating if a similar trend could be found in Sweden is therefore obvious. It was also important to add new knowledge to the bus and coach research in Sweden, since many areas were scarcely addressed. READ MORE

  4. 2. Vibrations, damping and power dissipation in Car Tyres

    Author : Martin Fraggstedt; Svante Finnveden; Ines Lopez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Acoustics; Akustik;

    Abstract : Traffic is a major source of green house gases. The transport field stands for 32 % of the energy consumption and 28 % of the total CO2 emissions, where road transports alone causes 84 % of these figures. READ MORE

  5. 3. High Frequency Tyre Vibrations

    Author : Patrik Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local deformation; adhesion; tyre model; air pumping; parameter study; tyre road noise; tyre road prediction models; tyre noise;

    Abstract : High frequency (above 1 kHz) noise generation from the tyre/road interaction is still not fully understood and accurately modelled.Two noise generation mechanisms previously suggested in the literature are reviewed: air pumping and noise generation cased by adhesive effects between the tyre tread and road surface.

  6. 4. Response of cable-stayed and suspension bridges to moving vehicles : Analysis methods and practical modeling techniques

    Author : Raid Karoumi; KTH; []
    Keywords : cable-stayed bridge; suspension bridge; Great Belt suspension bridge; bridge moving loads; traffic-induced vibrations bridge-vehicle interaction; dynamic analysis; cable element; finite element analysis; finite diffrence method; tuned mass damper; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis presents a state-of-the-art-review and twodifferent approaches for solving the moving load problem ofcable-stayed and suspension bridges. The first approach uses a simplified analysis method tostudy the dynamic response of simple cable-stayed bridgemodels. READ MORE

  7. 5. Belt Driven Alternator and Starter with a Series Magnetized Synchronous Machine Drive

    Author : Tomas Bergh; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electric Hybrid Vehicles, EHV, are under development to provide lower fuel consumption levels and minimize the environmental pollution compared to pure Internal Combustion Engine, ICE, driven vehicles. The EHV is more complex and thus carry many more extra parts than the pure ICE based vehicle. READ MORE
