Finite element analysis of the passenger side airbag deployment in Out-of-Position

摘要

In recent years many accidents happened with passengers that 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. The paper presents a simulation method for the deploying airbags using three materials in different working conditions. The deploying modeling of passenger side airbag is a complex and time consuming process. In these simulations the gas flow is described by the conservation laws of mass, momentum and energy. The main aim of this study is evaluate the performance of deploying of passenger side airbag using Finite Element Methods (FEM).
