1．數據導入matlab啟動Matlab軟件1.2點擊岀載入故障數據中的G2015,Workspace窗口出現：N：=uTie Value Class5G201S <100000x1double>double1.3取第一組數據G201，命令窗口輸入：G201=G2015(1:1:20000);2.數據預處理在測試中由數據采集所得的原始信號，在分析前需要進行預處理，以提高數據的可靠性和真實性，并檢查信號的隨機性，以便正確地選擇分析處理方法。預處理工作主要包括三個方面：一是除去信號中的外界干擾信號和剔除異常數據，如趨勢項和異點；二是對原始數據進行適當的平滑或擬合；三是對原始信號的特性進行檢驗。當然這些處理工作不是全部必需的，可以選—項或兩項內容，當認為原始信號獲取工作十分可靠或原始數據簡單可以直接判斷的情況下，也可以不進行這些預處理工作。以下所做數據預處理，故障軸承以G201為例，正常軸承以Z201為例，觀察原始數據經過不同方法做處理前后的變化。1.1零均值化處理(原理公式見報告P8)命令窗口輸入：G201I二G201-sum(G201)/20000;%G201l為零均值處理后的數據。“20000”為采樣點數。采樣點數 xw4從時域圖形上看，是波形整體在Y軸的平移。再看看頻域變化，命令窗口輸入:N=20000; %采樣點數fs=10000;%采樣頻率

f=(0:N-1)'*fs/N;%進行對應的頻率轉換G201p二abs(fft(G201));%進行fft變換,G201p為G201進行fft變換后結果G201lp二abs(fft(G201l));%進行fft變換，G201lp為G2011進行fft變換后結果subplot(2,1,1),plot(f(1:N/2),G201p(1:N/2));subplot(2,1,2),plot(f(1:N/2),G201lp(1:N/2));%顯示G201與G201p的頻譜圖得到下面圖形：從頻域圖可以明顯看出，零均值后消除?二0處出現一個由直流分量產生的大譜峰(將近達到4.5x104)，處理后避免了其對周圍小峰值產生的負面影響，便于頻域分析。消除趨勢項(原理公式見報告P10)使用最小二乘法，命令窗口輸入：t=(0:1/fs:(N-1)/fs)';%離散時間列向量G201x二polyfit(t,G201,6); %計算多項式待定系數向量G201x二G201-polyval(G201x,t);%用G201減去多項式系數生成的趨勢項,G201x即為消除趨勢項后的數據subplot(2,1,1),plot(G201);subplot(2,1,2),plot(G201x);%顯示G201與G201x得到以下圖形：G2011 1 1 1 1 r--□ 0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8 2采樣點數 x1Q4G201xI I I I I_3 I | | | | | | | | '"0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8 2采樣點數 x1Q4與前面零均值化處理中做頻域圖的方法一樣，做出G201與G201x的頻譜圖G201p與G201xp，得到圖形如下：從時域圖形和頻域圖形上看，消除趨勢項與零均值化處理的功能相似。不過，需要注意的是，它更重要的消除趨勢項，因為本數據中的多項式趨勢項很小，所以沒有明顯的變化平滑處理(原理公式見報告P11)使用五點三次平滑，命令窗口輸入：a=G201';fork=1:2b(1)=(69*a(1)+4*(a(2)+a(4))-6*a(3)-a(5))/70;b(2)=(2*(a(1)+a(5))+27*a(2)+12*a(3)-8*a(4))/35;forj=3:N-2b(j)=(-3*(a(j-2)+a(j+2))+12*(a(j-1)+a(j+1))+17*a(j))/35;end

b(N-1)=(2*(a(N)+a(N-4))+27*a(N-1)+12*a(N-2)-8*a(N-3))/35;b(N)=(69*a(N)+4*(a(N-1)+a(N-3))-6*a(N-2)-a(N-4))/70;a=b;endG201ph=a'; %G201ph為五點三次平滑法處理的數據subplot(2,1,1),plot(G201);subplot(2,1,2),plot(G201ph);%顯示G201與G201ph得到以下圖形：與前面零均值化處理中做頻域圖的方法一樣，做出G201與G201ph的頻譜圖G201p與G201php，得到圖形如下：從時域圖形上看，平滑處理使圖形變得平滑，去除毛刺，從頻域圖形上看，高頻部分明顯變少變小，而低頻部分基本無變化。因為故障的頻率主要集中在低中頻部分，這樣處理后不僅對故障的分析無影響，而且去除部分噪音，減少干擾。濾波處理(原理公式見報告P13)%使用巴特沃斯濾波器進行濾波，命令窗口輸入：wp=2400;%通帶截至頻率2400hzws=2800;%阻帶截至頻率2800hzrp=2;%通帶波動系數rs=60;%阻帶波動系數[N,wn]二buttord(wp/(fs/2),ws/(fs/2),rp,rs,'z');%建立巴特沃斯濾波器[num,den]二butter(N,wn);%建立數字濾波器[H,W]二freqz(num,den);%分析濾波器的幅頻特性plot(W*fs/(2*pi),abs(H));grid;%巴特沃斯濾波器頻率響應圖得到巴特沃斯濾波器頻率響應圖：繼續輸入：G201lb=filtfilt(num,den,G201);%G201lb為G201濾波后的數據subplot(2,1,1),plot(G201);subplot(2,1,2),plot(G201lb);%顯示G201與G201lb得到以下圖形：G201與前面零均值化處理中做頻域圖的方法一樣，做出G201與G201lb的頻譜圖G201p與G201lbp，得到圖形如下:在時域內不能明顯的看出處理前后的區別。但從頻域圖可以看出，2500Hz后的頻率幾乎不存在。因為低通濾波器的通帶截至頻率為2400hz，阻帶截至頻率為2800hz?？梢姙V波效果是很好的。以上介紹了一些數據預處理的方法，鑒于本文采集的原始信號數據較好，故只做零均值化這一項處理。3．時域特征值提?。ㄔ砉揭奝15）命令窗口輸入：
