등가모델을 이용한 커튼 에어백 장착 차량의 FMH 충격 해석

For protecting with the side impact and rollover crash, curtain airbag is being equipped increasingly in the vehicle. In order to provide the proper deploying performance, airbag shape design is important factor. But it also has to meet the FMVSS201 regulation of interior impact with the undeployed condition if not conducted the pole test. In this paper, new modeling method was introduced to curtain airbag. Folded and simply folded airbag model was good enough but time consuming in modeling and analyzing. So simple equivalent solid model was proposed and interior impact analysis with FMH was conducted and compared with the tests results
