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

    Författare :Astrid Linder; Chalmers University of Technology; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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. 3. Initial Studies of Dynamic Responses of Female and Male Volunteers in Rear Impact Tests

    Författare :Anna K Carlsson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; dynamic response; rear impact; response corridors; volunteers; crash test; neck injury; whiplash; females;

    Sammanfattning : Whiplash Associated Disorder (WAD) - commonly denoted whiplash injury - resulting from vehicle impacts, is a worldwide epidemic. These injuries occur at relatively low changes of velocity (typically between 10-25 km/h) and in impacts from all directions. Rear impacts are however the most common in the accident statistics.

  4. 4. Effects of Seat and Seat-Belt Design on Car Occupant Response in Frontal and Rear Impacts A Study Combining Mechanical and Mathematical Modelling

    Författare :Gert Nilson; Chalmers University of Technology; []
    Nyckelord :frontal impact; MADYMO; whiplash; rear impact; belt-in-seat; force-limiting; mathematical simulation; car seat; submarining;

    Sammanfattning : The objective of the present work is to determine the potential injury-reducing benefits to car occupants in accidents of seat and seat-belt design. The main problems addressed are the risk of injury to head, neck, and upper torso in frontal impacts, and the risk of minor neck-injuries - whiplash-injuries - in rear-end collisions. LÄS MER

  5. 5. Addressing Female Whiplash Injury Protection - A Step Towards 50th Percentile Female Rear Impact Occupant Models

    Författare :Anna K Carlsson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; anthropometry; dynamic response; head restraint; dummy; volunteers; whiplash; female; crash test; rear impact; neck injury; occupant model;

    Sammanfattning : Whiplash Associated Disorder (WAD) – commonly denoted whiplash injury – to vehicle occupants involved in collisions, is of worldwide concern. These injuries occur at relatively low velocity changes, typically between 10–25 km/h, and in all impact directions. Rear impacts are, however, the most common in the accident statistics. LÄS MER
