To minimize injuries of OOP condition is the most critical and important design point and development target of the passenger side airbag module. As a supplementary restraint system, PAB have been a help to reduce fatal injuries especially on frontal impact situation, however mid-mounted type PAB module also has a definite defect when is deployed with passengers side occupant of 6year or less infants(3year or 12 month) on OOP condition. Thus National Highway Transportation Safety Administration (NHTSA) makes Final Rule Making (FRM) including the concept of advanced airbag system which is required to reinforce safety performance for children or small sized occupant on out-of-position and all the vehicle makers who sell their vehicles in North America shall comply with FRM. Through evaluating the PAB design factors for mid-mounted position, it is recommended the most appropriate design guideline to protect passengers in OOP condition..<br/>
회주철 용탕 중 1.0 wt%Ba-Fe-Si 접종제의 성능에 미치는 S, Ce 및 Bi의 영향
권해욱 ( Hae Wook Kwon ),남원식 ( Won Sik Nam ) 한국주조공학회 2004 한국주조공학회지 Vol.24 No.5
N/A The effects of three minor elements, S, Ce and Bi, on the inoculation ability and fading behavior of 1.0 wt%Ba-Fe-Si were investigated through thermal analysis. The performance of 1.0 wt%Ba-Fe-Si inoculant was better and more consistant at the high temperature range of 1,450~1,500℃ than that of low one of 1,300~1,400℃. That was improved with individual addition of three minor elements. The optimum amount of addition was 1.0% of the weight of inoculant added, respectively. That was improved also by the simultaneous addition of two or three kinds of minor elements. Even though worse with the addition of two kinds of them simultaneously than with individual addition, that was improved with the simultaneous addition of all three kinds over that with the individual one.
