  1. 1. 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

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

    Författare :Manuel Mendoza-Vazquez; Chalmers tekniska högskola; []
    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

  4. 3. 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

  5. 4. Addressing Female Whiplash Injury Protection - A Step Towards 50th Percentile Female Rear Impact Occupant Models

    Författare :Anna K Carlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anthropometry; dynamic response; head restraint; dummy; volunteers; whiplash; female; crash test; rear impact; neck injury; occupant model;

    Sammanfattning : Whiplash Associated Disorder (WAD) – commonly denoted whiplash injury – to vehicle occupants involved in collisions, is of worldwide concern. These injuries occur at relatively low velocity changes, typically between 10–25 km/h, and in all impact directions. Rear impacts are, however, the most common in the accident statistics. LÄS MER

  7. 5. Performance and trainability in paraplegics : motor function, shoulder muscle strength and sitting balance before and after kayak ergometer training

    Författare :Anna Bjerkefors; Alf Thorstensson; Jan Fridén; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Balance; electromyography; exercise; kinematics; motor skills; paraplegia; postural control; shoulder joint; spinal cord injury; wheelchair;

    Sammanfattning : Background: Spinal cord injury (SCI) results in a complete or partial loss of motor and/or sensory function below the injury level. An SCI causes extensive functional impairment compelling many persons to wheelchair usage. LÄS MER
