详细分析了航空器内人员应急疏散模型中人的行为和运动过程、事故场景的危险性对人的行为影响、机组和舱内设施对人员疏散的影响等方面的特点,并全面讨论了这些模型的仿真与事故场景和全尺寸实验的验证对比结果。提出了航空器内人员应急疏散模型应该包括航空器几何模型、人员特征模型、人员行为模型、火灾模型和人员运动模型等5个子模型,以及各子模型的研究内容。同时,提出了人的行为描述和人的运动过程的计算机实现方法是影响紧急状况下人员疏散模型准确性的两个关键问题。研究结果表明:模型仿真在航空器的辅助设计、乘客的疏散优化和机组的应急程序开发等方面有应用价值,但模型的有效性验证困难限制了其更进一步的应用。
The characteristics of computer simulation model of occupant emergency evacuation in aircraft were analyzed according to occupant's behavior and movement, and the influence of accident scenario hazards on human behavior, and the influence of evacuation facilities and crew instruction on occupant evacu- ation. And comparisons were made in qualitative validation between the model simulation results and real accident scenario, and in quantitative one between the simulation results and full-scale evacuation. Then, an emergency evacuation model for occupants in aircraft and its content were presented, which includes five sub-models such as geometric model of aircraft, occupant feature model, human behavior model, fire model and human movement model. The description of occupant emergency behavior and the simulation of occupant movement were the two important bottlenecks influencing the aceuraey of models. Study shows that the results gotten by model simulation are beneficial to the computer-aided design of aviation, optimi- zation of occupant evacuation and development of aircrew emergency procedure, but the difficulty in the validation of the model makes a limitation of their application.
