机舱区域人员疏散仿真分析

Evacuation simulation for cabin crew

[目的]机舱人员在疏散过程中,需要考虑人员的行为和属性以及机舱的空间状态,因此具有很多不确定性因素。[方法]通过对人员模型结构进行功能划分,确定人员疏散模型的结构,建立人员属性模型,制定人员避让规则;通过对机舱的空间模型进行划分,绘制机舱环境结构并确定各子环境的安全等级,对机舱中出现的障碍物进行仿真表达和数学表达,以适用于三维仿真软件的计算。通过三维疏散仿真软件,对单人疏散路径和多人疏散路径分别进行仿真,模拟特定情况下各工作区域的机舱人员对路径的选择。[结果]仿真结果表明,该机舱疏散模型可以较准确地模拟人员的疏散过程。[结论]研究成果可为机舱的辅助设计提供参考依据。

[Objectives]This paper researches on the evacuation of cabin crew which has a number of uncertainties.During evacuation,the behavior and attributes of personnel and the space state of the cabin should be considered.[Methods]Through the functional division of the personnel model structure,the personnel evacuation model structure is determined,the personnel attributes are modelled,and the rules of personnel protection are established.Through dividing the cabin space model,plotting the cabin environment and grading the safety of subenvironments,the obstacles in the cabin are simulated and represented mathematically for the calculation via the 3D simulation software.Then by 3D evacuation simulation software,simulation tests for both single and multiple evacuation paths are carried out respectively.Besides,the selection of evacuation paths by the personnel in different working areas under specific condition are simulated so as to calculate the distance and time of evacuation.[Results]The simulation results show that the evacuation model of the cabin crew can simulate the evacuation process accurately.[Conclusions]The research findings provide basis for the auxiliary design of the cabin.
