對振沖處理效果和質量,採用了開挖檢查,樁體動力觸探檢測,樁間士初、川:貫入試驗及取樣試驗等方法對施土效果和質量進行檢測。Abstract : in order to process signal in depth and to extract the fault feature from original signal in machinery diagnosis , the graphical display algorithm that can keep the data length of wavelet transform results the same as that of original signal is used. the fault diagnosis of a bend axial piston pump via b - spline wavelet that has linear phase is provided. the results of study demonstrate that the new method has excellent feature and the weak fault signal can be extracted from the strong vibration background of the pump
文摘:採用具有線性相位的b樣條小波,應用圖形顯示演算法並結合小波變換快速演算法將信號分解到不同的頻帶上,且分解結果和原信號長度保持一致,可對信號進行深層次的處理,克服了傳統的信號處理方法不易提取微弱信息的不足.通過對礦用斜軸式柱塞泵振動信號的分析,分離出了配流副磨損、球鉸松動、缸體及泵軸支撐軸承的故障特徵,為液壓泵的故障診斷提供了依據,並為信噪分離、微弱信號提取及設備的早期故障診斷提供了一條有效途徑
