  1. 11. Car-to-Car Side Impacts: Occupant Injuries, Test Methods, and the Development and Evaluation of Protective Systems

    Författare :Yngve Håland; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The present work addresses the problem of injuries following car-to-car side collisions. The injuries in this type of impact have been evaluated to form the basis for the development of test methods and for the principles of protective systems. Side impacts give rise to relatively more severe injuries than frontal impacts. LÄS MER

  3. 12. Optimization of empty freight car distribution in scheduled railways

    Författare :Martin Joborn; Warren B. Powell; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In a railway system, empty freight cars have to be repositioned to enable transportation demand to be fulfllled. These empty car movements are planned and implemented in the empty freight car distribution process. LÄS MER

  4. 13. Simulation driven product development applied to car body design

    Författare :Nicklas Bylund; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : This thesis deals with the development of complex mechanical structures, from concept to detail design, as applied to car bodies. Efforts have been made to clarify how computer tools and analysis methods are used in product development in industry today. LÄS MER

  5. 14. Urban driving patterns - characterisation, variability and environmental implications

    Författare :Eva Ericsson; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Samhällsvetenskaper; Social sciences; Teknik; Technological sciences; speed limit; intersection density; driver age; gender; car performance; GPS; traffic flow; street environment; fuel consumption; deceleration; speed; acceleration; power demand; gear changing; exhaust emission;

    Sammanfattning : Driving patterns, i.e. the speed and acceleration profiles of vehicles affect exhaust emission and fuel consumption considerably. LÄS MER

  7. 15. A Framework for Analyzing the Operative Performance of Sequential Module Flows

    Författare :Peter Fredriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operative performance; module assembly units; sequential module flows; unit of analysis; output criteria; car industry;

    Sammanfattning : This thesis deals with sequential module flows (SMFs) and their operative performance. In brief, an SMF denotes the preassembly of components into product modules, which are delivered to a final assembly line in the same sequence as product variants are assembled. LÄS MER
