3. 2. 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

4. 3. Structural Safety Design for Real-World Situations - Using Computer Aided Engineering for Robust Passenger Car Crashworthiness

   Författare :Linus Wågström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; structural adaptivity; passive safety; small overlap crashes; crash compatibility; frontal crashes; structural robustness; crash simulation;

   Sammanfattning : Road traffic continues to cause more than a million fatalities worldwide every year. Although many steps have been taken to improve occupant protection in car crashes, challenges still remain for car designers. LÄS MER

5. 4. 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 tekniska högskola; []
   Nyckelord :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 ;

   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

7. 5. 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
