舒适性作为民机客舱设计的主要准则之一,对民机客舱舒适性进行客观合理的评价对提高我国自主研制的大型飞机市场竞争力具有重要的意义。针对目前评价方法中缺乏相应的数学评价模型这一问题,本文提出了基于多级模糊综合评判的民机客舱舒适性定量评价方法。在建立了民机客舱舒适性多级评价指标体系的基础上,采用层次分析法确定各级指标权重。针对民机客舱舒适性评价语言、评价标准以及评价过程中的模糊性、主观性,利用多级模糊评判矩阵对客舱舒适性进行评价,最终得到了较客观的定量评价结果。该结果同时可以对设计进行反馈,并指导设计调整过程,是一种有效的舒适性定量评价方法。
As one of the main criteria for the design of civil aircraft cabin, comfort is objectively and reasonably evaluated for the comfort of civil aircraft. It is of great significance to improve the competitiveness of the large-scale aircraft independently developed in China. In view of the lack of corresponding mathematical evaluation model in current evaluation methods, this paper presents a quantitative evaluation method of cabin comfort based on multi-level fuzzy comprehensive evaluation. Based on the establishment of multi-level evaluation index system of civil aircraft cabin comfort, the analytic hierarchy process is adopted to determine the weight of indicators at all levels. Aiming at the comfort evaluation language and evaluation criteria of civil aircraft cabin and the fuzziness and subjectivity in the assessment process, the cabin comfort is evaluated by using multi-level fuzzy evaluation matrix, and the objective evaluation result is finally obtained. The result can also feedback the design and guide the design adjustment process, which is an effective quantitative evaluation method of comfort.
