FMVSS226 Ejection Mitigation Impact Test is usually performed by real vehicle. But it is necessary to perform the test using by Reinforced B.I.W. with considering vehicle developing timing and roof rail airbag (RRAB) supplier capacity. We sometimes need tendency (quick data) instead of slow accurate data to fix RRAB design as proper timing. Test with Reinforced B.I.W. is helpful saving time and cost. But it should be confirmed how much different between vehicle conditioned test result and Reinforced B.I.W. conditioned test result. There are some points to be improved even in the test with vehicle. Understanding of deviation of Reinforced B.I.W. conditioned test result from vehicle conditioned test result is needed to get benefits with using Reinforced B.I.W. conditioned in the test.
Hybrid III 50<SUP>th</SUP> Percentile Featureless Headform의 가속도 값에 영향을 미치는 주요인자에 관한 연구

A special Hybrid III 50th Percentile headform is needed to perform the FMH Impact Test, which is one of the legal tests of North America. The Featureless Headform (i.e., a Hybrid III head without nose) should be used to cope with the US regulation that requires the headform’s forehead make initial contact with vehicle interior parts. To validate the headform’s effectiveness a head drop test is performed by means of evaluating its acceleration peak value after soaking the headform in a test environment for a period of at least 4 hours prior to the test. If the headform’s acceleration characteristic does not satisfy the requirement, a big loss cannot be evaded. So in order to eliminate this loss and to understand headform’s acceleration characteristics better, we first defines factors that affect the peak resultant acceleration of the headform when it is conducted the drop test and study how each factor affects the peak acceleration’s variance quantitatively using DOE and FE Analysis.

Child restraint system is very important and essential for the child passenger’s safety in case of vehicle crashes. Mortality can be reduced when CRS is used correctly. Based on NHTSA crash data in 2010, 655 children (age 12 and younger in a passenger vehicle) were killed in motor vehicle traffic crashes in USA, 64% of whom were restrained. About 75% CRS are not as secure in the car as they should be because their car seats are not being used correctly. This fatality rate could be reduced by about half if the correct child safety seat were used. NHTSA is planning a new consumer information program of CRS fitment for near future due to the importance of CRS installation. Purpose of this study is to identify factors affect CRS fitment and the influence of such factors. Objective evaluation method for CRS fitment test was also studied.
