摘　　要：在民用飞机市场竞争中,乘客的乘坐舒适性至关重要。为提升民用飞机的振动舒适性,增强中国民用飞机的市场竞争力,本文从民用飞机设计流程上为解决民用飞机振动问题提出方法及思路。首先,结合中国具有自主知识产权的支线客机ARJ21和大型客机C919的商业运营,详细介绍了目前中国自研民用飞机存在的主要振动问题。其次,分析了民用飞机的多源振动特性及其在机体上的传递路径,并介绍了多源振动贡献量分析方法和舱内振动舒适性评价方法。随后,为了在民用飞机设计阶段首先考虑振动舒适性要求,提出了基于多源振动贡献量分析的两级减振指标分配流程,并构建了民用飞机振动舒适性设计的基本思路。最后,展望了民用飞机振动舒适性设计的研究方向,探讨了提升乘客乘坐舒适性的技术措施及思路,以期为中国民用飞机的振动舒适性设计提供有益启示。In the competition of the civil aviation market,passenger comfort is paramount.In order to improve the vibration comfort of civil aircraft and enhance the market competitiveness of Chinese civil aircraft,this article proposed methods and ideas for solving civil aircraft vibration problems from the perspective of civil aircraft design process.Firstly,based on the commercial operation of China′s domestically developed regional aircraft ARJ21 and large aircraft C919 with independent intellectual property rights,the main vibration problems of China′s self-developed civil aircraft were introduced in detail.Secondly,the multi-source vibration characteristics of civil aircraft and their transmission paths on the body were analyzed,and the methods of multi-source vibration contribution analysis and cabin vibration comfort evaluation were introduced.Subsequently,in order to prioritize vibration comfort requirements in the design phase of civil aircraft,a two-stage vibration reduction index allocation process based on multi-source vibration contribution analysis was proposed,and the basic idea of civil aircraft vibration comfort design was constructed.Finally,the research direction of vibration comfort design for civil aircraft was prospected,and the technical measures and ideas to improve passenger comfort were explored,in order to provide useful inspiration for the vibration comfort design of Chinese civil aircraft.
