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
  4. Under the horizontal earthquake action and wind force, aim at " the pure frame structure with rectangle columns ", " the pure frame structure with special - shaped columns ", " the frame - truss structure with special - shaped columns " and " frame - shear wall structure with special - shaped columns ", earthquake action analysis was done by the spacial finite element method through the changes structural parameter. analyzing systematically " structure vibration mode ", " vibration period ", " structure lateral rigidity ", " seismic action force ", " seismic response force ", " floor seismic shear force ", " lateral horizontal displacement of structure " and " members internal force ". results indicate : ( 1 ) based on equal area, the special - shaped columns replaced the rectangle columns, the structural lateral rigidity enlarges, the lateral displacement minishes obviously, the earthquake response increase slightly, the biggest increasing amount of frame columns axis - compress ratio is smaller than 0. 08. the whole aseismic performance of structure has improved ; ( 2 ) when the section ' s length and section ' s thickness ratio of special - shaped columns is smaller than 3. 6, the structure benefits to resist seismic action ; ( 3 ) the angle of horizontal seismic action with the whole coordinate is 0 degree, structure earthquake response is bigger, belonging to a control factor of structure aseismic design ; ( 4 ) the frame - truss structure with special - shaped columns and the " a " - brace has the biggest lateral rigidity ; ( 5 ) the frame - shear wall structure with special - shaped columns have bigger lateral rigidity and smaller displacement, members internal force enlarged just rightly, have much superiority of resisting seismic action ; ( 6 ) in the higher seismic fortification criterion region ( 8 degree of seismic fortification intensity ), aseismic disadvantageous building site ( iii type site ), adopting special - shaped columns structure system, should reduce possibly the building ' s self - weight in order to reduce the earthquake response ; ( 7 ) the response spectrum method of computing seismic response and the time - history analysis method have similar analysis result

    西安理工大學碩士學位論文在水平地震作用下，並考慮風荷載組合，分別對「矩形柱純框架結構」 、 「異型柱純框架結構」 、 「異型柱框一析架結構」及「異型柱框-剪結構」等四種結構體系，通過改變結構參數，運用空間有限元方法，進行地震作用計算。系統地分析研究「結構振型」 、 「振動周期」 、 「結構側向剛度」 、 「結構地震反應力」 、 「樓層地震剪力」 、 「結構側向位移」 、 「層間位移角」 ，以及「構件內力」 。結果表明:在等面積原則下，異型柱代換矩形柱后，結構剛度增大，側向位移明顯減小，地震反應力略有增加，框架柱軸壓比最大增幅小於8 % ，結構整體抗震性能有所提高;當異型柱肢長肢厚比小於等於3 . 6時，結構有利於抗震;水平地震作用力與整體坐標夾角為0度時，結構地震作用效應較大，屬結構設計的控制因素之一;異型柱框一析架結構採用「人」字斜撐，側向剛度大於「八」字斜撐和「人一八」字混合斜撐;異型柱框一剪結構側向剛度大、位移小，構件內力增大適中，是一種抗震性能優越的結構體系:在抗震設防烈度較高地區（ 8度）和抗震不利的建築場地（ m類場地） ，採用異型柱結構體系時，應盡可能減輕結構自重，降低地震作用力;分別採用「振型分解反應譜」法和「時程分析」法進行地震作用計算，兩種方法所得結果基本一致。
