This work presents a novel algorithm for generating a geometric mesh of an airbag after a series of folds are defined on it, for use in crash simulations. The process of airbag folding is simulated as a series of geometric transformations to the airbag mesh, which is modeled as a stack of connected planar layers. Along with these transformations, optimization techniques are used to minimize cha...

background: balloon bionic midwifery has been applied in clinical obstetrics in china for 10 years, although played a certain role in controlling and improving the quality of obstetrics and caesarean section rate, but some questions have not been resolved. objective: the aim of this study was to investigate the efficacy and safety of airbag midwifery. materials and methods: primiparas (2410 cas...

A side collision of an automobile poses a higher risk of injury compared to those of a frontal collision. Therefore governments and insurance companies establish and implement new safety standards in order to ensure the safety of the occupants throughout the world. Most of the suggested standards aim to reduce the Head Injury Criterion (HIC). Widely used side airbag systems, including the curta...

Initial evaluation of the particle method for mathematical out-of-position simulations was performed. The evaluation was carried out by means of static inflation and impactor tests. In the out-of-position load case, the occupant is initially positioned very close to airbag module and the interaction airbag-occupant occurs during the early deployment phase of the airbag. Thus a realistic represe...

INTRODUCTION The global accident figures in Germany have been steadily declining for years now. This positive trend has been intensified by the extra protective effect afforded by front airbags. This additional protection of front airbags has been proven based on analyses of real accidents. The GDV airbag database has been expanded to 335 airbag cases and currently provides information about ac...

In an on-going research program, on the causation of injuries in motor vehicle accidents, at the University of Michigan Transportation Research Institute, crashes with airbags have been, and are continuing to be, investigated. In order to determine the occurrence, if any, of 'hearing problems' associated with airbag deployments, drivers and passengers who had been involved in 'airbag' automobil...

Airbag deployment has been known to be responsible for huge death, incidental injuries and broken bones due to low crash severity and wrong deployment decisions. Therefore, the authorities and industries have been looking for more innovative and intelligent products to be realized for future enhancements in the vehicle safety systems (VSSs). Although the VSSs technologies have advanced consider...
