Method for simulating passenger evacuation process under passenger cabin construction based on improved social force model

Abstract

The invention discloses a method for simulating a passenger evacuation process under passenger cabin construction based on an improved social force model. The method comprises the following steps: determining a passenger diameter and a passenger expected speed; determining an actual passenger cabin size, and reducing the passenger cabin size to obtain a passenger cabin size needed by simulation; and improving the modeling simulation of the social force model according to the passenger cabin size needed by simulation, the passenger diameter and the passenger expected speed to obtain passenger evacuation data under the passenger cabin construction. Through adoption of the method, a physical scene of the passenger cabin is enlarged by means of reducing an avoidance distance between a person and a wall, and emergent evacuation data are obtained by simulation in conjunction with the actual passenger diameter and the expected speed. As proved by simulation experiment comparison, the method has the advantages that the passenger evacuation time accuracy under original Anylogic simulation passenger cabin construction is increased greatly, and a result which is completely consistent with a simulation result of an airplane passenger cabin emergent evacuation model VacateAir can be obtained.

Description

technical field [0001] The invention belongs to the technical field of cabin safety emergency evacuation research, in particular to a method for simulating the evacuation process of passengers under a cabin configuration based on an improved social force model. Background technique [0002] The emergency evacuation of the aircraft cabin refers to the process of escaping the passengers in the cabin after an aircraft accident, and is a key factor affecting the safety of the aircraft cabin. The airworthiness regulations clearly point out that: For aircraft with a seating capacity of more than 44, the cabin configuration with the maximum seating capacity needs to be used, and the demonstration test proves that the cabin occupants and crew can be evacuated to the ground within 90 seconds. However, the demonstration test takes a long time, is expensive, and the test crew is extremely vulnerable to injury, and it is impossible to simulate the real accident state of the aircraft thr...

AI Technical Summary

Problems solved by technology

At the same time, severe oscillations and crossings occurred among the personnel, which did not conform to the reality of the evacuation of personnel in the cabin

This is because the repulsive and attractive forces experienced by the occupants in the cabin configuration have reached a "force balance" at a certain position, resulting in the occupants being stationary and unable to move forward to reach the seat

In addition, since the avoidance distance B between the person and the wall built in the model cannot be changed w , so the obtained results are inconsistent with the actual emergency evacuation data
