FMH 충격위치에 변화에 따른 머리 상해치 영향 평가

The FMVSS 201 regulation requires that the interior components in upper compartment of a passenger vehicle must satisfy Free Motion Headfoam (FMH) impact test with Head Injury Criterion (HIC) limit. Head Injury Criterion is influenced by many variables such as test velocity, FMH calibration performance, plan view angle, rotation angle and first contact position. In this paper, analytical research is carried out to find the effect of forehead impact zone and vertical approach angle in FMH Impact.
