“…Hence, manufacturers now incorporate a wide range of safety devices and features into their vehicles, including airbags, energy-absorbing steering columns, side door beams, etc. [6,13,26]. The seat belt is designed to restrain the occupant in the vehicle and prevent the occupant from having harsh contacts with interior surfaces of the vehicles.…”

In recent years, many accidents happened with passengers who were out of position when their airbag deployed. Therefore, new safety regulations have come into effect and an airbag now has to meet several requirements that concern out of positioning. In meeting these requirements, simulations of folding and deploying airbags are very useful and are widely used. This paper presents a simulation method for the deploying airbags using three materials in different working conditions. The main aim of this study is evaluate the performance of deploying of passenger side airbag using finite-element methods (FEMs). The model has been validated with experimental tests specifically designed for this task. Although the analysis was limited to linear elastic model, excellent agreements were obtained.

“…Hong 5 used a mix of dynamic experiments with finite element simulation-optimization techniques to backcalculate the elastic properties of 315 denier (60 Â 60) silicone-coated airbag fabric under deployment conditions. Hong discussed the anisotropy seen in uniaxial tests taken in the warp, fill and bias (yarns oriented at 45 degrees) directions in which Hong argued that this can be problematic in deciding the proper values to use for the mechanical properties in simulations.…”

In this paper the current generation of 350 dtex airbag coated and uncoated fabrics are examined experimentally under a multitude of simple and complex deformations. The geometric dimensions of the fabric architecture and the load–elongation behavior of the yarn constituents are studied. Furthermore, deformational shear behavior of airbag fabrics, which have not previously been investigated, are examined here. The stress–strain behavior of the yarn as well as the fabrics with and without coating are found to be highly nonlinear. Under uniaxial loading, nonlinearities of the fabric occur at lower strains due to crimp of the fabric, whereas under biaxial loading, the nonlinearity occurs at low and intermediate strain levels resulting from a combination of the inherent nonlinear material response of the yarn and geometric changes in the fabric structure. The data generated not only provide the basis for structural analysis of the airbag, but can also be used to develop more sophisticated definitions of the constitutive behavior of the fabric.
