  1. 1. Validity and reliability of vehicle collis : crash pulse recorders for impact severity and injury risk assessment in real-life frontal impacts

    Författare :Anders Kullgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; crash recorder; crash pulse recorder; impact severity; injury risk; real-life impacts; measurement accuracy; neck injuries; long-term consequences; reconstruction;

    Sammanfattning : The general objectives of this thesis were to study the importance of valid and reliable data from real- life collisions, especially the effects of inaccurate data on analyses of eg injury risks. Furthermore an objective was to develop and validate an on-board measurement device for acceleration measurements, to be used in reconstructions of primarily frontal impacts. LÄS MER

  2. 2. A safe road transport system : Factors influencing injury outcome for car occupants

    Författare :Helena Stigson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Crash pulse recorder; crash severity; injury prevention; real-life crashes; road safety; safety performance indicator; holistic;

    Sammanfattning : Given that over a million people are fatally injured in road accidents each year, the need for a systematic proactive approach is undeniable. The Swedish Road Administration (SRA) has developed a model for a safe road transport system based on the Vision Zero philosophy, to identify and prevent deviations from a safe system approach with regard to crashes.

  3. 3. 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

  5. 5. Whiplash Associated Disorders in Frontal and Rear-End Car Impacts - Biomechanical Guidelines and Evaluation Criteria based on Accident Data and Occupant Modelling

    Författare :Lotta Jakobsson; Chalmers University of Technology; []
    Nyckelord :neck injuries; rear-end impacts; frontal impacts; WHIPS; whiplash;

    Sammanfattning : Whiplash associated disorders, also called whiplash injuries or AIS1 neck injuries, represent one of the most significant types of injury in car crashes regarding both frequency and long-term consequences. The injury mechanisms are not fully understood, thus making it difficult to design and evaluate protection systems in cars. LÄS MER
