  1. 1. Head Injuries in Car-to-Pedestrian Accidents - Investigation of Head Impact Dynamics, Injury Mechanisms and Countermeasures

    Författare :Jianfeng Yao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accident analysis; head injury; head protection; mathematical simulation; accident reconstruction; injury mechanism; Pedestrian accident;

    Sammanfattning : The aim of this study was to investigate head impact dynamics and to establish risk functions for head injuries by mathematical reconstructions of real-world car-to-pedestrian accidents. Furthermore, an attempt was made to develop an approach for the design and evaluation of head-protective devices. LÄS MER

  3. 2. Investigation of Head Injuries in Car-to-Child Pedestrian Accidents

    Författare :Jianfeng Yao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; injury mechanisms; head injury; child pedestrian; accident;

    Sammanfattning : Head injury is the most common injury type in child pedestrian accidents andcould lead to lifelong disability or even death. To protect child pedestrianfrom head injury, it is important to understand the head injury mechanismsand tolerance levels. LÄS MER

  4. 3. Pedestrian Shoulder and Spine Kinematics and their Influence on Head Kinematics

    Författare :Ruth Paas; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PMHS; THUMS; kinematics; spine; head; shoulder; Human Body Model; pedestrian accidents; pedestrian;

    Sammanfattning : Pedestrian to vehicle crashes still represent a major health issue worldwide. In order to prevent fatalities and injuries during the in-crash phase of a pedestrian accident, a sound understanding of pedestrian in-crash kinematics is required and Human Body Models (HBMs) are valuable tools when studying such kinematics.

  5. 4. Numerical Accident Reconstructions : A Biomechanical Tool to Understand and Prevent Head Injuries

    Författare :Madelen Fahlstedt; Svein Kleiven; Peter Halldin; Michael Gilchrist; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Head injuries; Accident Reconstruction; Finite element analysis; Injury prevention; Helmet; Cyclist; Pedestrian; Epidemiology; Applied Medical Technology; Tillämpad medicinsk teknik;

    Sammanfattning : Traumatic brain injuries (TBIs) are a major health and socioeconomic problem throughout the world, with an estimated 10 million deaths and instances of hospitalization annually. Numerical methods such as finite element (FE) methods can be used to study head injuries and optimize the protection, which can lead to a decrease in the number of injuries. LÄS MER
