2. 11. Volunteer Kinematics and Muscle Activity in Dynamic Events Representative of Pre-crash Scenarios, Evaluation Data for Human Body Models

   Author : Ghazaleh Ghaffari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; volunteer; evasive manoeuvres; human body model; validation data; occupant kinematics; pre‐pretensioner belt; lane change; boundary conditions;

   Abstract : Advanced integrated safety technologies in modern cars such as collision avoidance intervention and pre-crash activated restraint systems involve comprehensive research on how vehicle occupants respond to these systems in pre-crash situations. Human Body Models (HBMs) are mathematical tools developed to predict human responses and injury outcomes in different pre-crash and in-crash situations. READ MORE

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

   Author : Manuel Mendoza-Vazquez; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element; Thoracic injury criteria; rib fracture; human body model; real-world crash data; survival analysis;

   Abstract : 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. READ MORE

5. 13. 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

6. 14. Seat integrated safety belts : a parametric study using finite element simulations

   Author : Anders Gavelin; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

   Abstract : In recent years an increasing interest has evolved concerning seat integrated safety belts in cars, regarding both 3- and 4-point belts in various configurations. One safety advantage of seat integrated safety belts appears in the case of so-called small overlap crashes. READ MORE

7. 15. In-plane Compressive Response of Sandwich Panels

   Author : Anders Lindström; Dan Zenkert; Stefan Hallström; Leif Carlsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Sandwich; Finite Element Analysis FEA ; Fracture; In-plane compression; Other engineering mechanics; Övrig teknisk mekanik; Structural and vibration physics; Struktur- och vibrationsfysik;

   Abstract : The high specific bending stiffness of sandwich structures can with advantage be used in vehicles to reduce their weight and thereby potentially also their fuel consumption. However, the structure must not only meet the in-service requirements but also provide sufficient protection of the vehicle passengers in a crash situation. READ MORE
