  1. 11. Postural and Muscular Responses of Car Occupants under Pre-Crash Conditions

    Författare :Ghazaleh Ghaffari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; vehicle occupant kinematics; pre-crash; evasive maneuvers; lane change; human body model; pre‐pretensioner belt; principal component analysis; linear mixed model;

    Sammanfattning : Advanced integrated safety technologies in modern cars such as collision avoidance intervention and pre-crash activated restraint systems require comprehensive research on how vehicle occupants respond to these systems. The aim of this thesis is to provide insights into car passengers’ body kinematics and muscle activations in representative pre-crash circumstances with respect to two belt configurations (i.

  3. 12. Occupant Neck Muscle Modelling in Rear-End Crashes

    Författare :I Putu Alit Putra; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Neck Muscle Responses; Finite Element; Whiplash Associated Disorders; Female; Human Body Model;

    Sammanfattning : The ultimate goal of the present research is to incorporate active and passive neck muscle effects in a female Finite Element (FE) Human Body Model (HBM). The application of interest is Whiplash Associated Disorders (WAD), which can occur in a low-speed rear-end impact. LÄS MER

  4. 13. Towards a human body model for prediction of vehicle occupant kinematics in omni-directional pre-crash events

    Författare :Emma Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pre-Crash Manoeuvres; Shoulder Muscle Control; Active Human Body Model;

    Sammanfattning : As the vehicle fleet becomes more equipped with crash avoidance systems, the proportion of crashes preceded by evasive manoeuvres is expected to increase. In an evasive manoeuvre, occupant position and posture can be influenced by the induced loading. Therefore, there is a need to predict the occupant response from evasive manoeuvres. LÄS MER

  5. 14. Fatal car crash configurations and injury panorama : with special emphasis on the function of restraint system

    Författare :Mats Lindquist; Ulf Björnstig; Anders Kullgren; Umeå universitet; []
    Nyckelord :Surgery; Deep studies; fatal crashes; small overlap; human FE-modeling; body kinematics; real life safety; Kirurgi; kirurgi; Surgery;

    Sammanfattning : Background: Most traffic safety research projects require accurate real world data which is collected in different databases around the world. This is especially important since the results of these projects form the basis for new crash test procedures and standards. LÄS MER

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

    Författare :Karl-Johan Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; 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
