Summary:After a survivable crash 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 airplane in a horizontal attitude, the airplane attitude is susceptible to tilt in the event of a reversible accident, and there is not enough research on the evacuation of airplane 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 airplane is established based on experimental statistics in order to analyze the impact of the tilted cabin on the evacuation of passengers after an airplane accident. A model of personnel movement in the tilted state is then added to the conventional social force model to create a simulation model of the evacuation of passengers. To analyze the spatial distribution of bottlenecks and time for passenger evacuation for various inclination attitudes brought on by accidents.
