  1. 1. Rib and Thoracic Response in Frontal Car Crashes: A Study Using a Finite Element Human Body Model

    Författare :Manuel Mendoza-Vazquez; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Frontal crash; THUMS; thoracic injury criteria; Finite Element; Human Body Model; rib fracture;

    Sammanfattning : Traditionally, restraint systems have been evaluated with Anthropomorphic Test Devices (ATDs) and the thoracic injury criteria have been based on parameters assessed using ATDs, such as chest compression. ATDs have limitations since they are only a gross representation of the human body. LÄS MER

  3. 2. 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

  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. Chest Injuries in Heavy Vehicle Frontal Collisions - Evaluation and Adaptation of the Hybrid III Dummy Instrumentation and Injury Reference Values by Means of Human Body Modeling

    Författare :Kristian Holmqvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMOS2; Human Body Model; Hybrid III; Frontal Crash; Finite Element; THUMS; Injury Criterion; Heavy Vehicle;

    Sammanfattning : The safety of passenger cars has been significantly improved during the last decades. Similar improvements are not as apparent in heavy vehicles and one of the reasons is believed to be deficiencies in heavy vehicle crash testing and the tools used to evaluate the biomechanical responses.

  7. 5. Heavy Vehicle Crash Safety - Improved Thoracic Injury Prediction in Frontal Crash Testing

    Författare :Kristian Holmqvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element modelling; Pendulum test; Injury assessment; Accidents; Chest injury; Hybrid III; Heavy goods vehicle; THUMS; Crash test;

    Sammanfattning : Frontal crashes are regarded as some of the most injurious accidents for Heavy Goods Vehicle (HGV) drivers. One of the leading HGV manufacturers regularly conducts frontal crash testing for occupant safety. The Hybrid III crash test dummy was developed for frontal testing in passenger cars and has become the standard in crash laboratories. LÄS MER
