基于信息熵的客机倾斜姿态应急撤离评价
Emergency evacuation assessment of aircraft tilting attitude based on information entropy
摘要
Abstract
To explore and evaluate the emergency evacuation effectiveness of passengers under different tilt attitudes of aircraft,an emergency evacuation evaluation model was established using information entropy theory.Evaluation indicators for emergency evacuation were constructed,and wide-body aircraft tilt attitude emergency evacuation simulation experiments were conducted using real evacuation test data.The entropy weight-technique for order preference by similarity to an ideal solution(TOPSIS)method was employed to assess and rank the effectiveness of emergency evacuation.The experimental data showed that the influence of tilt attitude on evacuation time ranged from −7.32%to+3%.With the speed entropy peak focused in the early stage,there were notable disparities in pitch and roll attitudes in the personnel density at exits 2 and 3.Analysis indicated that the speed entropy and exit personnel density were two crucial factors affecting the effectiveness of emergency evacuation in tilted attitudes.The evacuation performance was optimal at a pitch angle of 5°and worst at a pitch angle of −10°,showing opposite evacuation effects at tilt angles of 5° and 10°.As a guide for the safety evaluation of wide-body aircraft design,production,and operation,the established model for aircraft is capable of rating and evaluating various tilt attitudes.关键词
