fault-like feature
解釋
斷層狀構造-
The reassigned smoothed pseudo wigner - ville distribution ( rspwvd ) is introduced, which has less interference and higher resolution than other time frequency distributions like wigner - ville, choi - williams etc. it is used to detect the multi - knocking of engine such as cylinder, piston pin, valve, crank bearing, connecting rod bearing and jib knocking. a new fault diagnosis technique based on the rspwvd for the engine multi - knocking problem is proposed. by comparing the bispectrum and bicoherence of the gear vibration signals, it is demonstrated that bispectrum has an advantage over bicoherence for feature extraction of such signals
第四章首次引入一種重分配方法，得到干擾項少而解析度高的重分配平滑偽魏格納維爾分佈（ rspwvd ） ；對發動機曲軸主軸承響、連桿軸承響、活塞銷響、活塞敲缸響、氣門響和挺桿響等常見機械異響故障振動信號特徵進行了全面地比較分析；通過對各種異響故障特徵信號的分析研究，提出基於rspwvd的發動機多異響故障診斷策略，利用該策略可以準確識別不同的發動機異響故障。 -
2. the feature of geochemical primary halo in longshujiao ore segment shows that there is a positive abnormality of fi set of main chemical elements at 96 ~ 100 investigating line, longshujiao fault and fault 11 - 29, a east - north a positive abnormality of fs set of main chemical elements around 98 investigating line, big area positive abnormality of f4 set of main chemical elements in east ore segment and the feature of this abnormality is like the shape of the main ore - body in the west
2 、龍樹腳礦段構造原生暈特徵分析顯示， f _ 1主元素因子組在96 100勘探線，龍樹腳斷裂至? 29號斷裂間出現一個因子得分高值異常； f _ 5因子組以98勘探線為中點，因子得分值形成一個北東向高值異常； f _ 4因子組元素因子得分在東礦段形成大面積異常區，異常特徵與西部主礦體地表展布相似。 -
In this paper, the application of neural network fault diagnosis expert system to centrifugal oil delivery pumps is studied concretely based on a discuss deep on the feature of centrifugal oil delivery pumps ; and this paper puts forward a new idea of building combined neural network, which is composed of basic neural networks just like back propagation neural network and competitive neural network based on self - organization and self - adaptation
接著對神經網路的一些基本知識、發展概況、在故障診斷方面的應用情況作了簡要的介紹。本文在深入討論離心輸油泵故障診斷特點的基礎上，具體研究了神經網路故障診斷專家系統在離心輸油泵故障診斷上的應用，並且提出了基本網路分層聯接，不同基本網路層對應不同徵兆的組建神經網路的思路。
