  • In order to protect occupant during car crash accident, Regulation and NCAP(New Car assessment Program) have been developed among various countries like U.S.A., Europe, Korea and Australia. Especially NCAP scores affect to sales of vehicles. So vehicle makers are trying to get good score in NCAP. Low leg injuries play an important role in Australia and Euro NCAP and these injuries are related with footrest design. Optimization of footrest design in early stage of vehicle development is necessary to obtain better and robust results of low legs during crash tests. In this paper, DFSS method and finite element model were used to optimize the low leg performance in small RHD vehicles. Compared with the lower leg injury of base model, the lower leg injury of proposed model was slightly improved and robustness was enhanced also.

  • The side impact test in the Korean New Car Assessment program (KNCAP) has been conducted since 2003. The side impact test method has been contributed to the improvement of the vehicle side structure and the enhancement of the occupant protection performance for the domestic vehicles. The pole side impact test method introduced in the KNCAP in 2010 to enhance the head protection under the severe side crash environment. The pole side impact test is optional for the additional score to be added to the overall rating score. The test results of side and pole side impact test for five vehicles were introduced and compared.

  • Whiplash is the most frequent injury among occupants in low speed rear-end car collision. The aim of this paper is to analyze thecorrelation between influence parameters of head restraints and whiplash injury criteria.In this paper, DFSS (Design for Six Sigma) method is used for optimum design of head restrains. Four control factors of head restraints have selected by function matrix method. The effects of the control factors have been experimentally evaluated by using a sled pulse from 16km/h relative velocity which is suggested by KNCAP (Korean New Car Assessment Program). In order to reduce the noise factors of dynamic tests, whiplash tests were repeated twice. By using DFSS, the correlation between control factors and injury criteria has been comprehended.

  • Recently, Child safety has become one of the issue with Q10 dummy representing large child. The objective of this paper was to evaluate performance of three child restraints system (backless booster, high-back booster and without booster) by changing D-ring location in the rear seat. Sled tests were carried out with a Q 10 in 64km/h frontal impact. Before the dynamic sled tests, we assessed dummy positioning with difference in CRS types and height adjustment positions. Dynamic sled test results indicated that there is different performance of CRS types and belt routing. These test results will use as base line data for development CRS safety performance for Q 10.

  • 좋은 고기를 얻기 위해서는 도축하기 전에 가축을 가능한 한 안정시키지 않으면 안 된다. 소와 돼지는 도축장에 출하될 때 거의 트럭에 실려 오는 것이 일반적인데 운송도중에 차안에서 타박상을 입거나 골절되는 경우가 많기 때문에 주의가 필요하다. 뿐만 아니라 시간을 절약하기 위해 적정두수를 벗어나 과도하게 많이 적재하는 경우가 많기 때문에 여름과 같이 온도가 높은 때는 질식사하는 가축도 발생한다.

  • 여름은 여행이 많은 계절이고 운전을 하는 경우가 많기에 허리통증을 호소하는 사람들이 늘고 있다. 장시간 주행을 하다보면 운전자들은 한 자세로 고정되어 있어 혈액순환이 잘 안되어 목과 어깨에 무리가 따르게 되고, 허리가 아프며 가속과 정지를 많이 하게 되어 다리에 피로감을 느끼게 된다. 따라서 장거리 운전 중에도 차안에서 할 수 있는 간단한 스트레칭과 여행 중의 피로를 풀어주는 스트레칭으로 피로를 풀어보자.

  • Recently, the driver can be assisted by the advanced active safety devices such as ADAS from road traffic risks. With this system, driver and passenger may freed from can driving tasks or kept eyes on forward direction while on the road. Help from adoptive cruise control, auto parking and newly develped automated driving vehicles technologies, the driver positions will vary significantly from the current standard driver position during the travel time. On this hypothesis, the objective of this study is analyze the behavior and injuries of drivers in the event of frontal impact under these abnormal driver position. Based on the KNCAP frontal impact testing method, this simulation matrix was set-up with dummies of 5 th tile female Hybrid III dummy and 50 th tile male Hybrid III dummy. The small sedan type passenger car was modeled in this simulation. The series of simulation was performed to compare the injuries and behaviour of each dummy, varying the seating status and seat position of each dummy.

  • In proportion to increasing interest in vehicle safety, many country have regulated vehicle safety and performed NCAP(New Car Assessment Program). However vehicles which had good results in these compliance and NCAP frontal crash test have caused problems such as the fork effect and over-riding in real car-to-car accidents. To complement these issues, new frontal crash test modes using new barrier like FWDB and PDB have been developed by EEVC WG15. In this paper, FWDB frontal crash test was performed and the result was compared with the full frontal crash test using the rigid wall in order to comprehend the characteristic of FWDB. The results of FWDB test were compared with one of USNCAP and KNCAP. Using USNCAP data, vehicle performance like deformation and wall force were studied. A comparative study of dummy injuries was made by using KNCAP result. The results showed that vehicle performance of FWDB test like displacement and effective acceleration was similar in spite of absorbing energy of FWDB due to the greater vehicle deformation of rigid wall test. In FWDB test, driver dummy head bottomed out but most of injuries were superior to the injury of rigid wall test.
