  1. 1. Neck injuries in rear impacts : Dummy neck development, dummy evaluation and test condition specifications

    Författare :Astrid Linder; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neck; Injury; Anthropometric dummy; Severity; Impact test; Rear end collision; Seat; Mathematical model; Velocity; Thesis; Optimization; Mathematical neck models; Rear impact tests; Biomechanics; Road: Components of the vehicle; Road: Components of the vehicle;

    Sammanfattning : The objective of the work underlying this thesis was firstly to develop a neck for a new rear impact dummy, to evaluate the complete dummy and to specify test conditions for a consumer test with attention to AIS 1 neck injuries in rear impacts. In the development of the dummy neck, a mathematical neck model was developed and evaluated. LÄS MER

  3. 2. Development of a Mechanical Model for Rear Impacts: Evaluation of Volunteer Responses and Validation of the Model

    Författare :Johan Davidsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; whiplash; validation; rear impact; dummy; seat; spine; rear-end collision; volunteer; BioRID; neck;

    Sammanfattning : The objective of this research has been to develop a biofidelic crash-test dummy to facilitate design of seat systems with enhanced occupant protection in rear-end collisions. These frequent collisions may cause soft-tissue neck injuries to occupants in struck vehicles. LÄS MER

  5. 4. Child Safety in Car Crashes

    Författare :Marianne Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reconstructions; near-side; evaluations; frontal impact; rigid body; mathematical simulations; rear seat; finite elements; belt positioning booster; side impact; child safety; child seat;

    Sammanfattning : Traffic related trauma is the most common cause of fatality and severe injury to children in developed countries. The majority of these fatalities and injuries are caused by frontal and side impacts. LÄS MER

  7. 5. Comfort climate evaluation with thermal manikin methods and computer simulation models

    Författare :Håkan O. Nilsson; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; equivalent temperature; subject; thermal manikin; mannequin; thermal climate assessment; heat loss; office environment; cabin climate; ventilated seat; computer model; CFD; clothing-independent; comfort zone diagram; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Increasing concern about energy consumption and the simultaneous need for an acceptable thermal environment makes it necessary to estimate in advance what effect different thermal factors will have on the occupants. Temperature measurements alone do not account for all climate effects on the human body and especially not for local effects of convection and radiation. LÄS MER
