  2. 1. Effects of Seat and Seat-Belt Design on Car Occupant Response in Frontal and Rear Impacts A Study Combining Mechanical and Mathematical Modelling

    Author : Gert Nilson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frontal impact; MADYMO; whiplash; rear impact; belt-in-seat; force-limiting; mathematical simulation; car seat; submarining;

    Abstract : The objective of the present work is to determine the potential injury-reducing benefits to car occupants in accidents of seat and seat-belt design. The main problems addressed are the risk of injury to head, neck, and upper torso in frontal impacts, and the risk of minor neck-injuries - whiplash-injuries - in rear-end collisions. READ MORE

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

    Author : Fredrik Törnvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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 ;

    Abstract : 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. READ MORE

  5. 3. Child Safety in Car Crashes

    Author : Marianne Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reconstructions; near-side; evaluations; frontal impact; rigid body; mathematical simulations; rear seat; finite elements; belt positioning booster; side impact; child safety; child seat;

    Abstract : Traffic related trauma is the most common cause of fatality and severe injury to children in developed countries. The majority of these fatalities and injuries are caused by frontal and side impacts. READ MORE

  7. 5. Neck injuries in rear impacts : Dummy neck development, dummy evaluation and test condition specifications

    Author : Astrid Linder; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neck; Injury; Anthropometric dummy; Severity; Impact test; Rear end collision; Seat; Mathematical model; Velocity; Thesis; Optimization; Mathematical neck models; Rear impact tests; Biomechanics; Road: Components of the vehicle; Road: Components of the vehicle;

    Abstract : The objective of the work underlying this thesis was firstly to develop a neck for a new rear impact dummy, to evaluate the complete dummy and to specify test conditions for a consumer test with attention to AIS 1 neck injuries in rear impacts. In the development of the dummy neck, a mathematical neck model was developed and evaluated. READ MORE
