Abstract

This paper is a purpose to study the failure examples for a large bus vehicle fire. The first example, the researcher certified the fact that the absorbing material break away from the upper side of engine room because of weaken durability and the fire was produced in engine. The second example, it sought the fact that the fire breaks out by electric short because of over-load of compressor. The third example, it found the fact that the fire took place by heating of bellows upper part that was connected with muffler and exhaust manifold. The fourth example, it knew the fact that the fire occurred because of the electric short inside junction box of crash body part that was located to driver seat rightside. Therefore, the fire of a large bus occurring by decrepit of absorbing material and electric short have to thoroughgoingly manage the damage and dangerousness if it happens.

이 논문은 대형버스의 화재에 관련된 고장사례를 고찰한 논문이다. 첫번째 사례는, 엔진룸 상단에 부착된 흡음재가 노후되어 떨어지면서 엔진쪽에 화재를 발생시킨 것으로 확인되었다. 두번째 사례는, 컴프레서의 부하로 인해 전기적인 단락에 의해 화재가 발생한 것으로 확인되었다. 세번째 사례는, 머플러 상단에 부착된 흡음재가 떨어져 배기매니폴드와 연결되어 있는 머플러 상단에서 점화되어 화재가 발생된 것으로 확인되었다. 네번째 사례는, 운전석 우측 크래쉬 보디부의 졍션 박스내에서 전기전인 쇼트가 발생하여 화재가 발생된 것으로 확인되었다. 따라서, 대형버스의 화재는 흡음재의 노후, 전기적인 단락에 의해 화재가 발생하였을 경우 피해가 크고 대단히 위험하므로 철저하게 관리하여 화재 발생이 없도록 하여야 한다.
