中文摘要	为预测点型感烟火灾探测器的响应信号时程,提出了采用FDS软件进行数值风洞实验、标定探测器Cleary迟滞模型参数的方法和步骤。以JTY-GD-1109A光电散射感烟探测器为例,标定了与之匹配的Cleary迟滞模型参数;结合FDS火灾模拟分析结果,给出了适用于顶棚射流速度0.15~0.6m/s的探测舱内响应信号时程预测模型;通过一个室内火灾模拟算例,说明了该预测模型的应用。为评估点型感烟火灾探测器火灾探测的有效性提供了数值方法。; To predict the time history response of spot-type smoke detectors to fire signals,a parameter calibration method for the Cleary time lag model is proposed based on numerical wind tunnel experiments using the fire dynamics simulator(FDS) code.The JTY-GD-1109A light scattering smoke detector is used as the detection.Calibrated parameters of the detection's Cleary time lag model and the analytical results from the FDS fire simulations were combined to develop a model to predict the fire signal time history response in the sensing chamber,which is applicable to ceiling jets with velocities of 0.15-0.6 m/s.Predictions for a typical room fire agree well with the actual conditions in numerical tests.; 国家“十一五”科技支撑计划项目(2006BAJ13B03-02)
