摘　　要：在小尺寸ISO 9705锥形量热平台进行了不同尺寸的发泡聚苯乙烯燃烧实验,选择长、宽、高均为10 cm的EPS立方体为一个实验单元测量发泡聚苯乙烯燃烧热释放速率。提出基于高斯函数的、不考虑燃烧物理过程的热释放速率曲线预测模型。涉及的燃烧热物理性能包括热释放速率峰值、热释放速率峰值时间、火灾时间宽度,同时发现了总释热量与可燃物数量的幂函数关系,借助参数之间的关系可以对大尺寸物体燃烧结果进行简单预测。Combustion experiments of expanded polystyrene with different sizes were carried out on ascaled ISO 9705 cone calorime ter.The experiments took a block of 10 cm×10 cm×10 cm as a unit and measured the value of heat release rate.A method without con sideration of combustion procedure based on Gaussian function was proved to predict HRR curve of expanded polystyrene.The thermo physical properties include the maximum HRR,time to reach the maximum HRR,fire duration time.The function relationship be tween total energy content and the number of combustibles was found.The combustion with large scale can be predicted roughly considering the relationships between parameters.
