  1. Because reciprocating pump has complicated structure and more exciters, so its signal is a strong non - stationary signal, and carrying out fault feature extraction and diagnosis is very difficult to it, this text mainly researches on featute extraction of reciprocating pump ’ s valve vibration signal. this text introduces hht that huang put forward, it is a kind of signal processing method that suits for dealing with the stationary signal, and suits for non - stationary signal also. although the hilbert - huang transform ( hht ) is an effective tool processing the non - stationary signal, the hht based on emperical mode decomposition ( abbreviated as emd ) algorithm which adopts the cubic spline interpolation could n ' t acquire accurate characteristics for the strong non - stationary signals in that the spline produces an accurate result only under the condition that the data consists of values of a smooth function

    本文引入了huang等人提出的hht , hht是一種既適合於處理穩信號也是一種適合於處理非穩信號的信號處理方法。盡管希爾伯特-黃變換( hht )是處理非穩信號的有效工具,但基於經驗模態分解(簡稱emd )的hht由於採用三次樣條插值而不能準確提取強非穩信號的特徵,因為三次樣條插值只有在由光值構成的情況下才能產生精確的結果。為了解決這個問題,本文提出了基於改進的emd演算法,即採用分段三次hermite插值多項式( pchip )作為極值包的方法。
