摘要
为探讨不同舱门开启条件下空客A330客舱人员疏散特性,使用Pathfinder软件数值模拟,探究全部舱门开启、应急舱门无法开启、前客舱门无法开启、后客舱门无法开启4种情形下的人员疏散特性.研究发现:全部舱门开启条件下人员疏散用时63.3 s,应急舱门无法开启时人员疏散用时118.3s,3、4、7、8号舱门的人流量每秒分别下降0.09、0.2、0.09、0.04人,公务舱门和后客舱门出现堵塞.前客舱门无法打开时,人员疏散用时64s,从3、4、5、6号舱门撤离人数分别为47、48、52、50人,表明前客舱门无法开启未对疏散时间造成显著影响.后客舱门无法开启时,人员疏散用时112.3 s,从3、4、5、6号舱门第一个人撤离到最后一个人撤离的时间间隔分别为67.7、67.6、109.9、107.1 s.这表明经济舱乘客更倾向于从5、6号舱门逃生,从而延长了疏散时间.研究结果对掌握不同舱门开启条件下人员疏散特性提供了参考.
Abstract
To study the evacuation characteristics in the Airbus 330 cabin crew under different hatch opening conditions,the Pathfinder software was used to simulate the evacuation characteristics.The evacuation characteristics of personnel were explored in four situations:all cabin doors opened,emer-gency doors could not be opened,front cabin doors could not be opened,and rear cabin doors could not be opened.The results show that the simulation time for evacuation is 63.3 s when all hatches are open,while 118.3 s when the emergency hatch cannot be opened.The per-unit-time flow of people at No.3,No.4,No.7,and No.8 hatches decreases by 0.09 people,0.2 people 0.09 people,0.04 people re-spectively.It takes 64s to evacuate people when the front cabin door could not be opened.The number of people evacuated from No.3,No.4,No.5,and No.6 doors are 47,48,52,and 50 respectively,indicating that the failure to open the front cabin door does not have no significant impact on the evacuation time.When the rear cabin door could not be opened,the evacuation time is 112.3s.The time interval from the first person to the last person from the No.3,No.4,No.5 and No.6 doors is 67.7 s,67.6 s,109.9 s and 107.1 s,respectively.This indicates that more passengers in the economy class choose to escape from the hatches No.5 and No.6,which increases the evacuation time.The research results provide a reference for understanding the evacuation characteristics of personnel under different hatch opening conditions.
