Abstract

Entry speed of the vehicle and lateral acceleration acting on the vehicle, roll-angle associated with the overthrow, and then the structure of the road, the friction of road surface are important factors in turning on the curved road. In this study, we analyzed the state change of the vehicle causing entry speed of the vehicle and superelevation of the road, the friction coefficient by using a PC-crash Program for traffic accident reconstruction. As a result, when vehicle is turning the curved road, we could ascertain that the structure of the road and state of the road surface are a major factor about the set up of limited speed.

차량이 곡선도로를 선회함에 있어 차량 내부적 요소인 차량의 진입속도, 차량에 작용하는 횡가속도, 전복과 관련된 롤 각, 그리고 외부적 요소인 노면과 타이어와의 마찰 및 도로의 구조는 중요한 요소이다. 본 연구에서는 교통사고 재현을 위한 PC-Crash프로그램을 이용하여 차량의 진입속도와 도로의 편경사, 노면상태에 따른 마찰계수를 변수로 두어 선회 시 차량의 상태변화를 분석하였다. 그 결과로, 곡선도로 선회시 한계속도 설정에 관해 도로구조와 노면상태에 따른 마찰계수가 중요한 요소가 된다는 것을 확인하였다.
