타격 위치 산포를 고려한 운전석 무릎 상해 저감에 관한 연구

다국어 초록 (Multilingual Abstract)

Knee bolster structure reducing driver’s femur load should be designed to get more than 5 star rating in US NCAP and satisfy FMVSS 208 during vehicle collision. However, although an optimal knee bolster design is applied by FE simulation, occupant’s femur load sometime exceeds safety criteria in sled test. One of dominant factors that make a difference between simulation and test is knee impact position. In reality, knee impact points of sled test could not be exactly coincident with that of FE simulation and have some distributions according to test environments. Therefore, it is necessary to consider a scattering of impact points of sled test. In this paper, a knee bolster design was derived by FE simulation which considered statistically knee impact position using EDR method which was very efficient and accurate for reliability analysis.
