Abstract

In order to accurately evaluate the movement state and evacuation efficiency of passengers in the process of evacuation, make the social force model applicable to the emergency evacuation environment with closed aircraft cabin and dense seats, and simulate the steering and avoidance behavior of passengers in the process of evacuation, a modified social force model based on the aircraft cabin was proposed. This model introduced the steering factor and the avoidance factor, and obtained the comprehensive factor after the weighted average to correct the evacuation speed of passengers. The kinematic-mechanics dynamic equation of the social force model was improved. The correction range was obtained by the theoretical numerical analysis to the key parameters of the modified social force model. Taking a partial cabin of a certain plane as an example, a simulation experiment with 9×6 seats and a single channel was established to simulate the cabin environment. The results show that the simulated evacuation time is consistent with the experimental evacuation time, and the modified social force model is a continuous model of four factors, namely the prediction principle, subjective psychology, movement state and stress state, which can highlight its superiority in the application of emergency evacuation in aircraft cabin. © 2022 China Safety Science Journal.
