中文拼音 [fēijīshòumìnggūsuàn]
飛機壽命估算
英文
aircraft life evaluation-
Based on the aircraft structure fatigue theory, the article discussed the theoretical basis of methods that are usually used for aircraft structure fatigue crack - forming life estimation, i. e. the stress severity factor approach ( normal stress approach ), the local stress & strain approach, detail fatigue rating approach ( dfr ). also the processes of life estimation of these approaches are studied in the article
文章在簡要介紹飛機結構疲勞強度理論的基礎上，對目前飛機結構勞疲勞裂紋形成壽命估算常用的應力嚴重系數法（名義應力法） ，局部應力應變法，細節疲勞額定值dfr法的理論依據作了較詳細的論述，同時對這些估算方法進行壽命估算的過程與步驟也作了詳盡的闡述。Under these approaches, the 1if e of the lower flange connection region between a rib 6 and rib 8 of the front bar of some aircraft are estimated and the fatigue life of simulator of the connection region is experimentally tested and the estimation results and the experimental results are compared
通過用這些壽命估算方法對某型飛機前墻6 8肋段下緣條連接區進行壽命估算與該段連接區模擬試驗件進行疲勞試驗結果分別進行了分析比較。During the course of the life estimation, if the experimental parameters can be carefully chosen, aircraft structure life estimation has a positive effect on the structure fatigue des ign
在壽命估算過程中，只要比較精確地選取各方法所需的經驗參數，飛機結構所估算的最終結果對飛機結構抗疲勞設計和型號定壽有很大的指導意義。From the work done above, we can get the following conclusion " all these life estimation approaches can be smoothly used to predict the life of aircraft, but they have their own limits
通過上述工作，得到如下結論：各壽命估算方法都能較順利估算飛機結構的裂紋形成壽命，但各壽命估算方法又都有自身的缺點。The content includes the study on the fatigue performance of the plexiglas, the compiling of the load spectrum of the canopy, the study on the evaluation of the fatigue life of the canopy glass, the study on the allowable limit of the scratch on the canopy glass and the study on the analysis method of the dynamic response of the bird impact on the aircraft windshield
所涉及的內容包括:有機玻璃疲勞性能研究、活動艙蓋載荷譜編制、座艙玻璃疲勞壽命估算方法研究、座艙玻璃劃傷故障容限研究、飛機風擋鳥撞動響應分析方法研究等。根據活動艙蓋載荷特性，提出用壓力傳感器測量活動艙蓋載荷的方法，並首次實現了活動艙蓋載荷譜飛行測量。分享友人
