【摘要】:由于日益增長(zhǎng)的飛行安全和飛機(jī)維護(hù)質(zhì)量需求,飛機(jī)使用可靠性已經(jīng)成為一個(gè)重要的研究領(lǐng)域。從某航空公司波音737飛機(jī)使用過(guò)程中現(xiàn)場(chǎng)所記錄的18年的故障數(shù)據(jù)出發(fā),應(yīng)用奇異譜分析(SSA)方法,對(duì)故障時(shí)間序列進(jìn)行了建模和預(yù)測(cè),進(jìn)一步以預(yù)測(cè)結(jié)果的均方根誤差(RMSE)最小為優(yōu)化目標(biāo)對(duì)SSA模型參數(shù)進(jìn)行了優(yōu)選。在此基礎(chǔ)上,提出了一種更為廣泛的模型組合方法和實(shí)現(xiàn)算法,這種方法采用不同的時(shí)間序列模型來(lái)構(gòu)造SSA分解出的趨勢(shì)、周期和殘差等成分。通過(guò)與三次指數(shù)平滑(Holt-Winters)、自回歸移動(dòng)平均(ARIMA)2種時(shí)間序列模型的實(shí)驗(yàn)結(jié)果對(duì)比,SSA及其參數(shù)優(yōu)選和模型組合方法在故障時(shí)間序列分析中具有更好的擬合和預(yù)測(cè)精度。
[Abstract]:Aircraft reliability has become an important research field due to the increasing requirements of flight safety and aircraft maintenance quality. Based on the 18 year fault data recorded during the operation of a Boeing 737 aircraft, the fault time series was modeled and predicted by using singular spectrum analysis (SSA) method. Furthermore, the minimum root mean square error (RMSE) of the prediction results is taken as the optimization objective to optimize the parameters of the SSA model. On this basis, a more extensive model combination method and implementation algorithm are proposed. Different time series models are used to construct the trend, period and residual components of SSA decomposition. By comparing the experimental results with the two time series models of cubic exponential smoothing (Holt-Winters) and autoregressive moving average (ARIMA), SSA and its parameter optimization and model combination methods have better fitting and prediction accuracy in fault time series analysis.
