The Design And Simulation Study Of Emergency Evacuation Route In Aircraft Cabin Fire

The widespread use of portable electronic devices in the cabin has made fire incidents in aircraft cabins increasingly frequent.Because of the uncertain location of the fire source,a feasible method is needed to design the emergency evacuation route according to the location of the fire source,in order to provide rapid and reliable evacuation guidance for the relevant personnel in the cabin.Therefore,this thesis studies the design method of aircraft cabin emergency evacuation route in fire,and carries on the simulation verification to the designed route.Relevant results were obtained through the following work:(1)A full-size THREE-DIMENSIONAL model of A320 passenger cabin is established.The Fluent software is used to simulate the smoke diffusion situation of two different fire source locations,and according to the simulation results,the fire source location in the fifth row seat is selected as the basis for the subsequent evacuation route design.(2)Based on the environmental characteristics of aircraft cabin,the Cellular Automaton model is adopted as the theoretical model of evacuation route design.In order to make the model more consistent with the actual cabin environment,the cellular automaton is optimized and the influence of familiarity is added into the model.Two different evacuation routes are designed,and the evacuation process is simulated by Matlab in two dimensions to get the best evacuation scheme.(3)Use DELMIA software to conduct three-dimensional simulation of evacuation route,and know the main problems that should be paid attention to during evacuation,which further proves the availability of the designed evacuation route.Furthermore,the validity of designing emergency evacuation route is verified by using the ideas and methods in this thesis.
