Abstract

Road sides safety barrier system is the last safety during traffic accident. The structural performance of a roadside safety barrier should be kept above expectations. It is possible to protect the passenger's life. End treatment part is installed in the end of the barrier it prevents a phenomenon in which for the vehicle for the guardrail during a vehicle collision it is facility of the absorbing of car crashed impact. By repeated analysis through computer simulation for improving the vehicle crash it will be able to develop crash barriers to respond appropriately to various parameters.

차량방호울타리는 교통사고 발생 시 마지막 안전장치이다. 차량방호울타리의 구조적 성능이 기대 수준 이상으로 유지가 되어야지만 운전자 혹은 차량 탑승자의 생명을 보호해 줄 수 있게 된다. 단부처리시설은 방호울타리의 끝단에 설치되며 차량 충돌 시 가드레일이 차량에 관통하는 현상을 방지함과 동시에 충격을 흡수하는 형태의 시설물이다. 이러한 차량방호울타리의 개발을 위하여 컴퓨터 시뮬레이션을 통한 반복해석을 수행함으로서 다양한 변수에 적절히 대응하는 방호울타리를 개발할 수 있을 것이다.
