  1. 11. Head kinematics in car–pedestrian crashes: The influence of sliding, spine bending, elbow and shoulder impacts

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

    Sammanfattning : In vehicle–pedestrian crashes, head injuries account for an overwhelming percentage of all severe and fatal injuries. These injuries are caused by the linear acceleration and rotation of the head. To mitigate head injuries, tools such as Human Body Models (HBMs) are used in the development and evaluation of pedestrian safety systems. LÄS MER

  3. 12. 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

  4. 13. Understanding Boundary Conditions for Brain Injury Prediction : Finite Element Analysis of Vulnerable Road Users

    Författare :Victor S. Alvarez; Svein Kleiven; Peter Halldin; Ciaran Simms; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brain injuries; Vulnerable Road Users; windscreen impacts; Finite Element Analysis; pedestrian accidents; cycling accidents; pediatric neck; Applied Medical Technology; Tillämpad medicinsk teknik;

    Sammanfattning : Vulnerable road users (VRUs) are overrepresented in the statistics on severe and deadly injuries in traffic accidents, most commonly involving the head. The finite element (FE) method presents the possibility to model complex interactions between the human body and vehicles in order to better understand the injury mechanisms. LÄS MER

  5. 14. Modelling of Diffuse Brain Injury: Combining Methods to Study Possible Links between Transient Intracranial Pressure and Injury

    Författare :Ulrika Krave; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; animal model; astrocytosis; diffuse axonal injury; neurofilaments; diffuse brain injury; rotational acceleration; closed head trauma; rabbit; finite element analysis; intracranial pressure; injury mechanisms;

    Sammanfattning : The objectives of this research are the study of sagittal rotational acceleration induced diffuse brain injury mechanisms. Such injuries are common in vehicle accidents in particular; the consequences range from mild to severe symptoms and may lead to persistent neurological dysfunction. LÄS MER

  7. 15. Seat integrated safety belts : a parametric study using finite element simulations

    Författare :Anders Gavelin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : In recent years an increasing interest has evolved concerning seat integrated safety belts in cars, regarding both 3- and 4-point belts in various configurations. One safety advantage of seat integrated safety belts appears in the case of so-called small overlap crashes. LÄS MER
