基于油液光譜分析的PCA-AHP綜合傳動健康狀態評價研
摘要：油液光譜分析是研究綜合傳動運行狀態的重要方法,以油液光譜分析數據為基礎,運用主成分分析法(PCA)和層次分析法(AHP),建立了一種綜合傳動健康狀態的評價模型.文章結合機械設備健康的概念,綜合考慮油液光譜分析數據中各種磨損元素的影響,提出用健康值來定量描述綜合傳動運行狀態的概念,并根據健康值對綜合傳動健康狀態進行了等級劃分;利用主成分分析法,對油液光譜分析數據進行主成分提取的研究分析;運用層次分析法研究主成分權重值,探討判斷矩陣的構造、一致性檢驗等問題;然后將二者有機的耦合,建立評價模型;實驗研究表明,此方法具有很高的準確性,能夠有效地判斷綜合傳動的運行狀態,對開展綜合傳動狀態評估具有重要意義.Abstract：Spectrometric oil analysis is an important method to study the running state of power-shift steering transmission (PSST). An evaluation model of PSST health state was developed on the basis of the theories of principal component analysis (PCA) and analytic hierarchy process (AHP) using spectrometric oil analysis data. Considering the concept of mechanical equip-ment and wear elements in spectrometric oil analysis data, the health value was employed to quantitatively describe the running state degree of PSST, and the grades of health state were classified based on the health values. The oil analysis data were studied during the process of choosing principal components. The weight vectors of principal components were obtained by using the AHP method. In the course, the cortformation of judgement matrix and the consistency check were also studied. The evaluation model was developed by combining the PCA and AHP methods. This model has been proved to have better accuracy in evalua-ting the running state of PSST. This work is important for developing state evaluation of PSST. 作者： 張英鋒[1]馬彪[2]鄭長松[2]張金樂[2]范昱珩[3] Author： ZHANG Ying-feng[1] MA Biao[2] ZHENG Chang-song[2] ZHANG Jin-le[2] FAN Yu-heng[3] 作者單位： 北京理工大學機械與車輛學院,北京,100081;軍事交通學院汽車工程系,天津,300161北京理工大學機械與車輛學院,北京,100081中國兵器科學研究院,北京,100089 期 刊： 光譜學與光譜分析 ISTICEISCIPKU Journal： SPECTROSCOPY AND SPECTRAL ANALYSIS 年，卷(期)： 2010, 30(4) 分類號： U463.2 TH137.3 關鍵詞： 光譜分析 PCA-AHP 綜合傳動 健康狀態 Keywords： Spectral analysis PCA-AHP methodology Power-shift steering transmission(PSST) Health state 機標分類號： TP1 TK4 機標關鍵詞： 油液光譜分析 綜合傳動 健康狀態評價 Oil Analysis Based oil analysis analysis data 光譜分析數據 evaluation model principal component analysis analytic hierarchy process 主成分分析法 運行狀態 running 層次分析法 評價模型 judgement matrix the consistency 健康值 AHP 基金項目： 國防預先研究項目，高等學校學科創新引智計劃，總裝備部預研項目【基于油液光譜分析的PCA-AHP綜合傳動健康狀態評價研】相關文章：
