Searched restoration repair quality and accident danger after restoration repair of damage vehicles in<br/> this research. Non genuine parts are circulated much by the automobile repair parts recently. Therefore,<br/> analyzed performance of engine mounting member's genuine parts and non genuine parts that is<br/> extracted in part accident vehicles. Test results concluded ; Tensile strength of genuine part engine<br/> mounting member is higher than damaged non-genuine part engine mounting member. The chemical<br/> component at engine mounting member of 12 component was similar to that for genuine part and<br/> non-genuine part but the different that Ti, Ni component. Non-genuine part elongation is higher than<br/> genuine part. Non-genuine part hardness is higher than genuine part. Acts that can protect consumer<br/> interests about quality guaranty of repair vehicles in domestic is unprepared. Therefore, must set non<br/> genuine part's performance and quality standard for derive activation of non genuine parts market.<br/> Because introducing parts certification system, must non genuine part market to do bringing into the<br/> open and derive activation of parts market.

Since 2000, sports utility vehicles(SUVs) occupy about 40% of domestic vehicle sales. As sports utility vehicle sales are increased the probability of crash accident between SUVs and passenger vehicles increases. Generally, SUVs are heavier than passenger vehicles and their drive height and front end stillness are higher than passenger vehicles. Because of these characteristics SUVs cause more severe injury and fatal injury in SUV to passenger vehicle head-on impact. To evaluate SUV's aggessivity to passenger vehicle, we carried out SUV to passenger vehicle head-on crash test. And finally the way how to reduce incompatibility between SUVs and passenger vehicles is suggested.

We have found that the damage of the front part for a vehicle and that of the rear part for a vehicle are the majority of frequency experienced by the traffic accidents. In conventional bumper system was designed by safety standard regulation at low speed crash. For example there are 2.5 mile and 5 mile bumper. The conventional bumper system was the crash from max 5.5 mile to 3 mile low speed occurs most frequently and results in the highest rate of repairing cost in statistically. On this study, in order to check the damageability and repairability of gas tube bumper system, RCAR 15 km/h 40 % offset frontal crash test was adopted in low speed and we have a gas tube bumper parts test and vehicle test with gas tube bumper. we can find gas tube bumper system definitely can improve the damageability and repairability of the vehicles and contribute to down the repairing cost.

본 연구에 표본으로 선정된 에어챔버 충격흡수장치를 장착한 고위험군 사고차량의 손상정도와 형태를 분석하여 사고재현 충돌시험모드를 선정하고 충돌시험을 실시하여 시험결과를 분석한 결과 시험차량의 손상형태가 사고사례 차량의 손상형태와 동일성 또는 유사성을 나타내었다. 사고재현 충돌시험 모드는 IIHS(미국고속도로안전협회) 충돌시험 모드이고 상해위험분석 결과 종합등급 4등급 이상에 해당하며 약식상해등급 AIS 4이상의 상해위험성이 있는 것으로 분석되었다. 이로서 트럭용 에어챔버 충격흡수장치의 안전성능 즉 충격흡수 및 방호기능은 사망위험성을 크게 회피시키고 있음을 확인되었다. 사고사례를 분석한 결과 사고형태는 크게 3가지로 나타났으며 그 중에 후면 부분겹침충돌사고는 전체사고의 약 73%이다. 약식상해등급 AIS 4이상 상위 사망위험 비율은 약 63%에 해당하였다. 그 중에 AIS 5 이상 고상해위험사고 비율은 약 30%로 분석되었으며 트럭용 에어백 충격흡수장치의 사망사고예방 기여도는 고유의 충격흡수 성능으로 인해 약 75%이상 이디. 이는 사망사고 위험을 약90% 이상 줄여 줄 수 있다. 트럭용 에어챔버 충격흡수장치를 해당 장착차량 구조 및 작업환경에 맞추어 반드시 장착해야 추돌시고 시 언더라이더 현상을 막고 충격을 흡수하여 중대한 사상자를 줄일 수 있다. 따라서 도로 유지보수 및 사고차 처리 작업차량에 대해서는 트럭용 에어챔버 충격흡수장치(TMA)의 장착률을 높여야 한다. 특히 우리나라의 경우는 박스형 1톤 화물차 및 박스형 승합차 보급율이 미국이나 유럽 등 다른 나라에 비해 절대적으로 높아서 박스형 차량이 도로상에서 정지상태로 작업 중에 있는 고중량 작업차량 후면을 추돌할 경우 중대한 사고로 이어질 수 있으므로 작업용 차량에 트럭용 에어챔버 충격흡수장치 장착을 적극 권장한다. 특히 고속도로에서 충돌사고로 인해서 사망과 같은 심각한 사상자 발생을 감소시키기 위해서 작업구간 후방에 작업메뉴얼에 따라 안전관리구간을 확보하는 것이 매우 중요하다. The damage patterns of the high-risk accident vehicles equipped with air shock absorbers selected for this study were selected and the collision test mode was selected and the test results were analyzed, indicating the damage patterns of the test vehicles were identical or similar to those of the accident case vehicles. The collision test mode is IIHS (National Highway Traffic Safety Association) crash test mode, and the injury risk analysis indicates that the mode corresponds to Grade 4 or higher, and that it has a risk of injury higher than Grade AIS 4. It was thus confirmed that the safety performance of the air shock absorber for trucks, i.e. shock absorption and protection functions, have greatly avoided the risk of death. The analysis of accident cases showed that there were three types of accidents, of which the rear partial sinking collision accounted for about 73 percent of the total accidents. The upper death risk ratio of Class AIS 4 or higher was about 63%. Among them, a high risk accident rate of AIS 5 or higher was analyzed to be about 30%, and the contribution of the truck impact absorber to prevent death was greater than 75% due to its inherent impact absorption performance. This can reduce the risk of death by about 90 percent. The impact absorber for trucks must be fitted in line with the structure and working environment of the vehicle in question to prevent under-rider phenomenon and absorb shock to reduce serious casualties. Therefore, for road maintenance and accident handling vehicles, the mounting rate of the air shock absorber (TMA) for trucks should be increased. In particular, Korea strongly recommends fitting an air shock absorber for trucks to work vehicles because the rate of supply of box-type 1-ton cargo trucks and box-type passenger cars is absolutely higher than other countries, such as the U.S. and Europe, and if a box-type vehicle runs behind the rear of a high-volume working vehicle while working on the road, it could lead to a serious accident. In particular, it is very important to secure a safety management section in accordance with the work manual at the rear of the work section in order to reduce the occurrence of serious casualties, such as death, from a collision on a highway.
