정면충돌모의 시험을 이용한 뒷좌석 탑승객 안전성 평가 연구

Recently a lot of social attention to the safety of the car is being poured. The government secure the safety of the car through the car safety standards and NCAP (car safety rating system), and has been an effort to inform its performance. However, the current Motor Vehicle Safety Standards and the evaluation system have been made only by the front-seat. So, attention to the safety of rear-seat is relatively much inferior. The purpose of this paper was undertaken to confirm the status of the rear seat safety in frontal crash. In this paper, we selected two sedan and two SUV. And we also use the following dummies. [5% -ile female , 50% -ile male , 5% -ile pregnant female(MAMA) , 6 year-old child (Q6)]. According to standard of NCAP frontal crash safety test, we performed full frontal sled test twice. Test pulse used the average deceleration of the test pulse that used in the NCAP frontal crash safety test for a total of 30 vehicles. According to the test results, we found that the Injury criteria of rear-seat passenger is higher than that of frontal-seat passenger. Injury criteria difference between male and female were not large. But, Injury criteria of Q6(was seated in CRS) was lower than any other dummies.
