| Abstract: | The modeling of front passenger side airbag(PAB)based on CFD is described in detail.In accordanee with FMVSS 208 regulation,the process of contact between front out-of-position(OOP)occupant and PAB iS simulated with software Madymo,and the mechanism of injury caused by PAB iS analyzed.Then an improvement scheme of airbag with rupturable tether is proposed to alleviate the OOP occupant injury caused by PAB,and a corresponding simulation is conducted.The results show trhat the scheme can well achieve the effects of injury improvement. |
