B型地铁列车侧壁材料耐火性分析

Analysis of fire resistance of type B subway vehicle's wallboard material

以典型B型地铁车辆为研究对象,利用Pyrosim软件分别建立侧墙墙板材料为铝合金和玻璃钢的模型进行数值模拟仿真,并对两种模型发生火灾时车厢内部的热释放速率、温度、CO浓度进行对比,分析两种不同材料侧墙的车辆的火灾危害程度。结果表明:铝合金墙板侧墙具有更好的防火能力,火灾安全性更高。

In a typical type B subway vehicle as the research object, using simulation software Pyrosim established two simulation models, whose wallboard material of side wall was aluminum alloy and fiber reinforced plastic respectively. The fire hazard of the two kinds of model would be discussed by comparatively analyses of heat release rate, temperature and CO density. The results showed that： the side wall with aluminum alloy has better fire resistance, and the fire safety of the vehicle was higher.
