该文通过笔者在日常的工作中所遇到的具体实例,介绍了航空器高温管路中波纹管数量设计方法;同时也通过实例,分析了航空器高温管路中热应力产生的原因,管路热应力对航空器结构带来的破坏作用,以及高温管路中支撑固定系统的布置原则以及支撑形式选择进行了分析,提出了一种通过改变管路支撑系统的结构形式来有效预防管路热应力的设计方法。 This paper introduces the design method of the corrugated pipe number in the high temperature pipeline of the aircraft through the concrete examples that the author encountered in the daily work. At the same time, through examples, the causes of the thermal stress in the high temperature pipeline of the aircraft are analyzed. The destructive effect of stress on the structure of the aircraft and the arrangement principle of the supporting and fixing system in the high temperature pipeline and the choice of supporting forms are analyzed. A method is proposed to effectively prevent the thermal stress of the pipeline by changing the structure of the pipeline supporting system Design method
