  1. 1. Neck Injury Risk in Rear-End Impacts. Risk Factors and Neck Injury Criterion Evaluation with Madymo Modelling and Real-Life Data

    Författare :Linda Eriksson; Chalmers University of Technology; []
    Nyckelord :injury criteria; rear-end impacts; neck injuries; mathematical modelling; injury probability; head restraints; BioRID; NICmax; risk factors; WAD; car seats;

    Sammanfattning : Soft-tissue neck injuries, also termed AIS 1 neck injuries, are common after low-speed rear-end impacts. These injuries, which can be long-lasting, have increased in frequency during the past few decades. There is no consensus regarding injury mechanisms; however, injury criteria have been proposed, without yet being fully evaluated. LÄS MER

  2. 2. The Contribution of Vehicle, Occupant and Other Factors to the Risk of Injury as a Result of Vehicle Rollover

    Författare :Stephen Ridella; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intrusion; Kinematics; Injury Causation; Roof Inversions.; Rollover; CIREN; NASS-CDS; Restraints;

    Sammanfattning : Injuries and deaths as a result of vehicle rollover have been declining in recent years like other crash modes, but it still remains a consistently large contributor of the overall crash fatalities in the United States. Also, more new vehicles are becoming equipped with electronic stability control and are subject to new regulations that call for increased roof strength and countermeasures to prevent ejection during rollover crashes.

  3. 3. Traumatic Brain Injuries: Animal Experiments and Numerical Simulations to Support the Development of a Brain Injury Criterion

    Författare :Jacobo Antona; Chalmers University of Technology; []
    Nyckelord :traumatic brain injuries; traffic safety; concussions; animal experiments; finite element method;

    Sammanfattning : Traumatic Brain Injuries (TBIs) account for about half of the 1 300 000 annual traffic related deaths and the 50 000 000 injuries worldwide. The burden of TBI is ethically unacceptable and economically unsustainable. LÄS MER

  4. 4. Child Safety in Car Crashes

    Författare :Marianne Andersson; Chalmers University of Technology; []
    Nyckelord :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

  5. 5. 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
