In this paper, a physical and mathematical model of interaction between fabric expanding automobile airbag biological objects is formulated. Bioobjects are represented using finite element models anthropometric dummies the Hybrid III 50th Male type. As material, multi-layer orthotropic material was used. The method corpuscular particles used for numerical simulation functioning in LS-DYNA multi...

Development of frontal impact airbag sensor algorithms/calibrations requires crash signals, which can be obtained from vehicle crash testing and/or CAE simulations. This paper presents the development of finite element sensor models to generate CAE simulated crash pulses/signals at the sensing location during frontal impacts. These signals will be evaluated for potential used in the airbag sens...

The purpose of this study is to test the hypothesis that the upper cervical spine is weaker than the lower cervical spine in pure flexion and extension bending, which may explain the propensity for upper cervical spine injuries in airbag deployments. An additional objective is to evaluate the relative strength and flexibility of the upper and lower cervical spine in an effort to better understa...

IT components with information processing and communication capabilities are embedded in almost all commonplace and industrial objects. In our daily life we depend more and more on these IT components. On the other hand, users will increasingly expect that those IT components collaborate autonomously and thus provide emergent properties. Hence we have to guarantee their reliability, even though...

A case of choroidal rupture caused by airbag-associated blunt eye trauma and complicated with massive subretinal hemorrhage and vitreous hemorrhage that was successfully treated with intravitreal injection of expansile gas and bevacizumab is presented. A 53-year-old man suffered from loss of vision in his right eye due to blunt eye trauma by a safety airbag after a traffic accident. On initial ...

Fundamental physics and numerous field studies have clearly shown a higher injury and fatality risk for occupants in smaller and lighter vehicles when colliding with a heavier, taller and a higher one. The consensus is that the significant parameters influencing compatibility in front-toside crashes are geometric interaction, vehicle stiffness, and vehicle mass. The objective of this research i...
