Abstract:After a preventable catastrophe on the ground, emergency evacuation is a crucial means for airplane occupants to immediately flee danger. Although there has been a lot of research on emergency evacuation of aircraft in a horizontal attitude, the aircraft attitude is susceptible to tilt in the event of a reversible accident, and there hasn"t been enough research on the evacuation of aircraft occupants in an inclined attitude. A model of individual deceleration ratios and the sliding speed of various emergency slide angles under the tilted attitude of the aircraft was established based on experimental statistics in order to analyze the impact of the tilted cabin on the evacuation of passengers after an aircraft accident. A model of personnel movement in the tilted state was then added to the conventional social force model to create a simulation model of the evacuation of aircrew. To analyze the spatial distribution of bottlenecks and time for passenger evacuation for various inclination attitudes brought on by accidents. The findings indicate that in order to avoid overcrowding, it is crucial to promptly evacuate passengers who are in the upward-facing area of the cabin. To reduce the risks associated with overcrowding of occupants, special attention should be made to the evacuation of bottleneck exits in the cabin"s downward segment.
