A New Method for Rolling Element Bearing Fault Diagnosis Based on Cyclostationary Theory

引用

International Journal of Plant engineering and Management 2001年第3期6卷 136-142页

作者： JIANG Ming, CHEN Jin, QIN Kai The state key {2. of Vibration, Shock & Noise, Shanghai Jiaotong university, Shanghai 2.0030, P.R.china The state key {2. of Vibration Shock & Noise Shanghai Jiaotong University Shanghai 200030 P. R. China

The theory of cyclostationary and its application are very important for the analysis and processing of a non stationary signal. The paper introduces second order cyclostationary statistics, with emphass on discussion of cyclic periodogram arithmetic. Comparing the time smoothed cyclic periodogram with the frequency smoothed cyclic periodogram, we found that the former is more useful to extract the feature of cyclostationary signals. The method has been applied to analyze the vibration signal of a rolling element bearing measured on a test bench, and proved to be effective. Meanwhile, we have compared it with traditional power spectral density analysis, and the results prove that the time smoothed cyclic periodogram is more available to diagnose the fault of a rolling element bearing.

This paper studied a general class of nonlinearstochastic systems, which can be approximated by T-Sfuzzy model. The problem both the control and the stateentering into the diffusion term is discussed here. A PDCstate feedback controller is proposed to guarantee themean-square stability of the closed-loop system. All theresults are represented by the linear matrix inequalities.

Synthesis and assembly with mesoporous silica of platinum(II) porphyrin complexes bearing carbazyl groups:Luminescent and oxygen sensing properties

引用

Science Bulletin 2006年第19期51卷 2327-2334页

作者： HUO Cheng, ZHANG Huidong, GUO Jianhua, ZHANG Hongyu, ZHANG Ping & WANG Yue key laboratory for Supramolecular Structure and Materials of Ministry of Education, College of Chemistry, Jilin {2., Changchun 130012. china key laboratory for Supramolecular Structure and Materials of Ministry of Education College of Chemistry Jilin University Changchun 130012 China

A series of platinum meso-tetrakis [3-methoxy-4-(N-carbazyl)n-alkyloxyphenyl]porphyrin (Pt-4Cn-TPP, n = 4, 6 and 8) are synthesized. Pt-4C4-TPP, Pt-4C6-TPP and Pt-4C8-TPP exhibit similar luminescent properties in solution and solid state. Three protonated platinum (II) porphyrins are assembled with mesoporous silica MCM-48, respec- tively, resulting in assembly materials Pt-4Cn-TPP4+/ MCM-48 (n = 4, 6 and 8). The luminescent intensity of Pt-4Cn-TPP4+/MCM-48 can be extremely quenched by molecular oxygen with high sensitivity (I0/I100 > 9). The Stern-Volmer plots of these assembly materials display considerable linearity within a wide range of oxygen concentration (0 to 100%). The re- sponse time is all ≤ 1 s and recovery time ≤ 2. s for these assembly materials.

Structural, magnetic and transport properties of Sc-doped La0.7Sr0.3MnO_3

Chinese Science Bulletin 2000年第9期45卷 810-814页

作者： YAN Chunhua, HUANG Yunhui, WANG Zheming, ZHANG Lei, GAO Song, LIAO Chunsheng & XU Guangxianstate key {2. of Rare Earth Materials Chemistry and Applications, PKU-HKU Joint {2. in Rare Earth Materials and Bioinorganic Chemistry, Peking university, Beijing 100871, china state key {2. of Rare Earth Materials Chemistry and Applications PKU-HKU Joint Laboratory in Rare Earth Materials and Bioinorganic Chemistry Peking University Beijing China

The Sc-doped La0.7Sr0.3MnO3 polycrystallines were prepared by thermal decomposition of complexes of metal ions with ethylenediamine-tetraacetic acid (EDTA). The dependence of structural, magnetic and transport properties on Sc doping was investigated. Moderate Sc doping level results in a sharp drop in Curie temperature, an increase in resistance and enhancement of magnetoresistance effect. At temperatures above TMI, R(T) can be described as R(T) = R0exp(T0/T)1/4, which indicates that conduction takes place by hopping between the localized states. The experimental data reveal that the change in magnetoresistance property is related to the structure.
