摘要: 在现代先进飞机结构耐久性设计技术中,结构经济维修是一个重要方面.为了确保飞机结构的经济寿命和可靠性,必须制订合理的结构经济维修方案.本文详细地讨论了各种因素对确定飞机结构经济维修方案的影响及其确定原则,从工程实用的角度建立了以耐久性分析为基础的飞机结构经济维修方案优化方法.该方法考虑了修理后结构经济寿命估算的特点,给出了一个实际飞机结构修理方案制订的算例.Abstract: The aircraft structural economic maintenance is one of the important aspects in the durability design of advanced aircraft.To assure economic life and reliability of aircraft structure,an economic maintenance program is essentially needed.In this paper,the effect of various factors on the determination of aircraft structural economic maintenance programme and the criteria of determining these factors are discussed in detail.From the practical engineering application point of view,an analytical methodology for the optimization of aircraft structural economic maintenance programme based on structure durability analysis is presented.It also accounts for the feature of evaluating the economic life of the repaired structures.A practical structural maintenance programme,as an example,to demonstrate the application of the methodology is given.
