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

    Författare :Johan Davidsson; Chalmers University of Technology; []
    Nyckelord :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

  4. 4. 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

  5. 5. Car-To-Car Side Impacts: Development and Validation of Mathematical Models and their Usability for Protective System Design

    Författare :Bengt Pipkorn; Chalmers University of Technology; []
    Nyckelord :dummy; injury criteria; padding; mathematical simulations; barrier; side impact; car; occupant; airbag;

    Sammanfattning : The objective of the present work was to develop and use mathematical models to establish principles for protective systems for occupants in car-to-car side impacts. The efforts in this work have concentrated on the protection of the thorax and abdomen since these body parts are most frequently injured in side impacts. LÄS MER
