Improved side impact protection in the traffic of the future - car to car full vehicle crashes with WorldSID

Period
1 January 2009-1 January 2010
Project manager
Cecilia Sunnevång

Legal- and rating procedures for side impact protection has led to side airbags as standard equipment. Still, side crahses with serious and fatal outcome occur. Accident statistics has shown that these crashes occur at higher impact severities than what current restraint systems are designed for. The aim of this study is to, based on real-life data, develop test procedures including a more biofidelic dummy, better representing real-life crahses, and by a serie of full vehicle crashes present opportunities and possible improvements of side impact protection. The study consists of four work packages: 1) characterize real-life side crashes regarding severity, principal direction of force, road conditions and occupant; 2) test method development to better represent real-life crashes (incl. car-to-car crash with two moving cars); 3) evaluate occupant injury risk with WorldSID (hardware and FE-model); 4) indentify trends for future cars and traffic environment with significant influence on the nature of side collisions.

Thoracic Injury Risk as a Function of Crash Severity - Car-to-Car Side Impact Tests with WorldSID Compared to Real-life Crashes

Side airbags reduce the risk of fatal injury by approximately 30%. Due to limited real-life data the risk reducing effect for serious injury has not yet been established. Since side airbags are mainly designed and validated for crash severities used in

Effect of Side Impact Protection in Reducing Injuries

The aim of this study was to identify risk factors in side impact. In particular risk factors such as kerb weight of striking/struck passenger car, age, gender, the presence of a front-seat occupant and side airbags influence the injury outcome. The

Response of the Worldwide Side Impact Dummy 'WorldSID' to localized constant-speed impacts

The objective of this study was to evaluate WorldSID constant-speed shoulder and thorax impact responses in terms of impact force, external and internal deflection (1D and 2D IR-Tracc response) for two velocities (1 m/s and 3 m/s), at three impact levels
