| Abstract |
|
The heat release rate generated when a fire occurs in a railway vehicle is one of the most important factors when designing precautions for railway facilities such as railway tunnels. In this study, the fire characteristics of interior materials required to analyze the propagation of a fire in a new railway vehicle were identified via an experimental method. The fire characteristics of the main interior materials across various radiant heat fluxes were analyzed, and the ignition temperature of the interior materials was predicted using the heat release rate and ignition time. By predicting the ignition temperature, the critical heat flux and ignition temperature were confirmed to be low for the flooring of the main interior materials. The derived fire characteristics (ignition temperature and heat release rate) for each material can be used to analyze the fire propagation phenomenon in railway cars. |

철도차량에서 화재가 발생하였을 경우에 발생하는 열방출률은 철도터널과 같은 철도시설물의 안전설비를 설계하는데 가장 중요한 인자 중 하나이다. 본 연구에서는 신규 철도차량 내에서 화재가 발생하였을 경우의 화재전파를 해석하기 위하여 필요한 내장재 화재특성을 실험적인 방법으로 파악하였다. 주요 내장재에 대하여 다양한 입사열유속별 재료의 화재특성을 분석하였으며 이를 이용하여 내장재의 발화온도를 예측하였다. 발화온도를 예측한 결과, 주요 내장재 중 바닥재에서 임계열유속 및 발화온도가 낮게 나타남을 확안하였다. 도출한 재료별 화재특성(발화온도, 열방출률)은 철도차량의 화재전파 현상을 해석하는데 활용될 수 있다. |
