簡介：中國民用航空學院碩士學位論文摘要論文緊密結合航空發(fā)動機維修中的實際問題，對維修過程中的裝配間隙對發(fā)動機性能的影響進行統(tǒng)計分析，介紹了多元線性回歸的基本理論和方法，重點分析了發(fā)動機裝配間隙對風扇壓氣機和渦輪性能的影響。論文完成以下主要工作T收集了AMECO近年來維修的PW4000發(fā)動機的裝配間隙數(shù)據(jù)和試車數(shù)據(jù)，并對數(shù)據(jù)進行整理，以此作為統(tǒng)計分析的依據(jù)2用相關分析和逐步回歸方法選擇那些對發(fā)動機性能有重要影響的間隙，將選出來的間隙與EGT建立多元線性回歸模型和多元非線性回歸模型，通過計算以及對回歸模型的檢驗后，給出兩種模型下的擬合效果圖，繪出EGT隨間隙變化的性能曲線圖，最后還分別用兩種模型進行預測，得到合理的結果3通過逐步回歸方法選擇對發(fā)動機其余的性能參數(shù)如N2NT和WF有重要影響的間隙，將這些選出來的間隙與三個性能參數(shù)建立多元非線性回歸模型，通過計算和對回歸模型的檢驗后，給出在該模型下的擬合效果圖，繪出三個性能參數(shù)隨間隙變化的性能曲線圖，最后還分別用該模型對四個樣本進行預測，得到合理的結果4用逐步回歸方法選擇出對發(fā)動機的推力有重要影響的間隙，并建立間隙與推力之間的多元線性回歸模型并通過該模型進行預測，得到合理的結果結合課題工作，論文利用VC和ODBC數(shù)據(jù)庫開發(fā)了應用程序，通過該程序可以對EGT等航空發(fā)動機性能參數(shù)進行了分析，為評估、預測裝配間隙對發(fā)動機性能影響提供了參考，為以后發(fā)動機維修提供參考和指導。關鍵詞航空發(fā)動機間隙性能分析多元回歸分析一一一一一一一一一一一一絲韭遇碩士學位論文ACCORDINGTOTHEACHIEVEMENTOFTHEPROJECTANAPPLICATIONPROGRAMISDEVELOPEDBYVCLANGUAGEANDODBCDATABASESUCHPROGRAMCANBEUSEDTOANALYZETHEPERFORMANCEPARAMETERSSUCHASEGTN2N1ANDWEITALSOCANGIVESOMEREFERREDADVICEOFMAINTENANCEWHENTHEINFLUENCETHATTOLERANCECLEARANCESAFFECTEDAEROENGINEPERFORMANCEISESTIMATEDANDFORECASTEDKEYWORDAEROENGINETIPCLEARANCEPERFORMANCEMULTIREGRESSIONM
