摘要
客舱地板结构是民用飞机机身结构的重要组成部分,其中滑轨结构与客舱地板横梁连接,是比较关键的结构,直接承担着飞机旅客载荷以及座椅的载荷。首先介绍说明了民用客机地板结构的受力情况,其次针对目前国际典型机型的客舱地板滑轨结构形式、材料选材以及滑轨与横梁的连接形式等内容进行了分析说明,给出了各机型客舱滑轨结构形式的结构特点,再者从民用飞机客舱的滑轨冠部的设计、滑轨上缘条的设计以及滑轨高度的设计三个方面对客舱滑轨结构设计进行了分析与说明,给出了民用飞机客舱地板滑轨结构设计分析的要点和一般方法。最后对民用飞机客舱地板滑轨结构设计方案进行了总结归纳与分析,为民用飞机客舱地板滑轨结构设计提供参考和借鉴。
The cabin floor structure is an important part of the fuselage structure of civil aircraft.The seat rail is connected with the floor beam,which is a key structure and directly bears the loads of aircraft passengers and seats.Firstly,this paper introduces and explains the stress of the floor structure of civil aircraft,then analyzes and explains the structural form of the cabin floor slide rail of the current international typical aircraft,as same as the material selection and the connection form between the seat rail and the beam,gives the structural characteristics of the structural form of the cabin slide rail of each aircraft.Furthermore,the structural design of the cabin slide rail was analyzed and explained from three aspects:the design of the crown of the seat rail of the civil aircraft cabin,the design of the upper edge strip of the seat rail and the design of the height of the seat rail,and the key points and general methods of the structural design and analysis of the floor seat rail of the civil aircraft cabin were given.Finally,the structural design scheme of the cabin floor slide rail of the civil aircraft was summarized and analyzed.It provides a reference for the structural design of civil aircraft cabin floor slide rail.
