民用直升机金属结构环境损伤等级评定方法分析
|
摘要
直升机的工作环境极为恶劣,其金属结构的环境损伤等级研究是直升机维修间隔评估的重要内容之一。综合考虑了民用直升机的运营环境和金属结构的材料特性,根据现役民用直升机的使用特点,得到影响其金属结构环境损伤等级(environmental damage rate,EDR)指标,结合层次分析法(analytical hierarchy process,AHP)建立出一个三层三级的EDR指标评级模型——模型N。同时运用模型N和模糊层次分析法(fuzzy analytical hierarchy process,FAHP)的两种模型进行实例计算,发现运用模型N与经过FAHP两种模型处理的专家经验结果相近,验证了模型N的可行性,为民用直升机金属结构维修间隔评估提供工程依据。
The working environment of helicopter is extremely bad,and the research on the environmental damage rate of the metal structure is one of the important parts of the maintenance interval evaluation of helicopter. The operating environment of civilian helicopters and the material characteristics of metal structures were considered comprehensively. According the environmental damage types of metallic materials for civilian helicopters metal material environmental damage grade( EDR) index were obtained,as well as combining analytic hierarchy process( AHP) a three layers and three levels EDR index rating model-N were established. Then using model-N and two models of fuzzy analytical hierarchy process( FAHP) to carry out an example calculation,finding that the result calculated by model-N is closed to expert experience processed by the two models of FAHP,thus the feasibility of the model is verified,and it can provide engineering basis for evaluation of maintenance interval of civilian helicopter metal structure.
