Abstract

Automobile collision analysis is composed of various shapes, and the speed variation working to the vehicle during collision are utilized as a very important factor in evaluating the degree of vehicle collision or passenger safety. So, the method of analyzing result values on the speed variation utilizing collision analysis program become necessary. This study utilized PC-Crash program in order to compare actual values and analyzed values of braking distance with the friction coefficient of road surface according to vehicle velocity. As a result, the smaller friction coefficient found to be larger error, and the maximum error range of collision velocity in case of each different vehicles (MATIZ, SONATA, or BUS) at the intersection showed 1.2%, 1.8%, 3.1% according to the difference of vehicle weight. Moreover, an accidental fall at IN-CHEON large bridge in order to reappear was verified with practicing simulation which has a slight error.

자동차 충돌해석은 다양한 형태로 구성되어 충돌중 차량에 대한 속도변화는 차량간의 충돌정도 또는 승객의 안전도를 평가하는 데 중요한 요소로 활용된다. 이로 인해 충돌해석 프로그램을 활용한 속도변화에 따른 결과치를 해석하는 방법이 필요하다. 본 연구에서는 PC-Crash 프로그램을 이용하여 노면의 마찰계수에 따라 차량속도에 따른 제동거리를 실제값과 해석값을 비교하여 마찰계수가 작을 때 오차가 큼을 알 수 있었고, 서로 다른 주 차량(MATIZ, SONATA 및 버스 적용)이 교차로에서 충돌하는 속도의 오차범위는 차량무게의 차이에 따라 최대오차는 1.2%, 1.8%, 3.1%으로 나타났다. 또한 인천대교 버스추락 사고를 재현하기 위하여 시뮬레이션을 한 결과로 다소 오차는 있었으나 사고 재구성을 검증할 수 있었다.
