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

    Författare :Ruth Paas; Chalmers University of Technology; []
    Nyckelord :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

  2. 2. Evaluation of Shoulder-Complex Motion in Frontal and Oblique Impact Loadings - A Comparison between Frontal Impact Dummies and the Human Body

    Författare :Fredrik Törnvall; Chalmers University of Technology; []
    Nyckelord :Sled tests; Cadaver; Volunteers; Kinematics; Hybrid III; Static loading; Shoulder range-of-motion; Offset frontal collision; THOR; Shoulder; Biofidelity; Oblique frontal collision; Crash test dummy; Post Mortem Human Subjects PMHS ;

    Sammanfattning : Offset and angled frontal impacts represent a crash type that is more common than full-frontal collisions. Several studies have shown that over 70% of all frontal impacts are offset or oblique. LÄS MER

  3. 3. A New Shoulder for the THOR Dummy Intended for Oblique Collisions

    Författare :Fredrik Törnvall; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shoulder; Shoulder range-of-motion; Volunteers; Kinematics; Biofidelity; Post Mortem Human Subjects; THOR; Crash test dummy; Oblique collision;

    Sammanfattning : Offset and oblique frontal car collisions represent a type of crash in which severe and fatal injuries frequently occur. This indicates the importance of having protective systems in vehicles for these types of collisions. LÄS MER

  4. 4. Evaluation of Morphed Human Body Models for Diverse Occupant Safety Analysis

    Författare :Karl-Johan Larsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Diversity; Morphing; Validation; Virtual testing; Safety; Human body model;

    Sammanfattning : Female, obese, and elderly occupants are at increased risk of injury in vehicle accidents. Human Body Models (HBMs) are used to represent the human anatomy and to study injury mechanisms in mathematical crash test simulations. LÄS MER

  5. 5. Thoracic injuries in frontal car crashes: risk assessment using a finite element human body model

    Författare :Manuel Mendoza-Vazquez; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element; Thoracic injury criteria; rib fracture; human body model; real-world crash data; survival analysis;

    Sammanfattning : Accident data show that there is a clear need to improve the protection to occupants’ thorax in frontal car crashes. For this purpose, models that can predict the risk of injuries and assess the occupant protection offered by different restraint systems are needed. LÄS MER
