摘要: 飞机结构单独采用耐久性设计或者单独采用损伤容限设计都会影响飞机结构的最优化设计.针对此问题,在现有的飞机结构耐久性和损伤容限分析方法基础上提出了飞机结构耐久性/损伤容限综合设计与分析方法并建立了分析流程图.在保证结构安全和经济维修的前题下,提出了以飞机结构重量和检修一体化作为飞机结构优化设计的指标.该方法可用于新研飞机的设计和现役飞机寿命的可靠性评定分析,具有实用价值.

Abstract: Based on existing durability and damage tolerance analysis method, a new way of flight structure design and analysis by synthesis was presented. It solves the problem that designing with durability or damage tolerance method separately will affect the optimization design for the flight structure. The analysis flowchart of this method is also given. Besides of using life and safety analyzing, structural weight and the inspection and maintenance were discussed. It can be used to increase the maneuverability and economy of the new flight structure. In addition, a calculation example is presented to validate the feasibility of this new method.
