Modeling and Simulation of Bus Fire Accidents

Abstract

Fire accidents of buses, especially those ones often close the windows for equipped with air conditioner, have brought great threats on passengers’ lives and properties. It is important to make prepare for the fire emergency accidents. Because the fire accident of bus is very dangerous, and the virtual simulation is used to analyze the bus firing process instead of real tests so as to learn how to response to the emergency disaster in safety. The software named FDS is used to simulate the process of the bus-firing accident, which a running bus catch fire. Firstly, the whole simulation framework is built to guide the model process of the bus fire accident. Then, the height of smog layer, distributions of indoor temperature and carbon monoxide concentration from the bus firing accidents are analyzed by simulation way. The results of the simulation of the bus fire accidents show that the different distributions law of the fire factors in the fire accidents inside the carriage, and it is important to provide better reference to prepare for the fire emergency disaster.
