主成分分析是一种经典算法，可以利用其进行故障检测。利用主成分分析进行故障诊断的MATLAB程序，包括T2统计量和SPE统计量，进行故障检测与诊断的效果非常好。

降低轨道衡“顶轨”故障的技术方案与实施

从振动信号中提取故障特征是滚动轴承故障诊断的常用方法。提出了利用零空间追踪算法和包络谱分析进行滚动轴承故障诊断的方法。首先对轴承故障振动信号进行零空间追踪(Null Space Pursuit)分解,降低噪声的干扰,提取高能量成分。然后对高能量分量进行包络谱分析得到振动信号特征频率,与理论故障特征频率对比后确定故障类型。仿真和试验结果显示该方法能够成功提取特征频率,辨别轴承故障类型,具有一定的实际意义。

Complex Networks Toolbox for MatLab is designed to analyze large-scale graphs, model them, explore with simulations of dynamic processes and generate appealing and insightful layouts. example： function [BetweenneessCentrality, varargout]= GraphBetweennessCentrality(Graph,SourceNodes) % Computes betweenneess centrality of each node. % % Receives: % Graph - Graph Struct - the graph loaded with GraphLoad % SourceNodes - array of double - (optional) nodes, from which passes start. Default: [] (all nodes). % % Returns: % BetweenneessCentrality - array of double - Betweenneess Centrality for each node. % Nodes - array of double - (optional)List of all nodes for which betweennessn centrality is computed % % Algorithm: % http://www.boost.org/libs/graph/doc/betweenness_centrality.html % % See Also: % mexGraphAllNodeShortestPasses % warning('Use the more optimized mexGraphBetweennessCentrality.dll'); error(nargchk(1,2,nargin)); error(nargoutchk(0,2,nargout)); if ~exist('SourceNodes') | isempty(SourceNodes) SourceNodes = unique(Graph.Data(:,1)); end Nodes = unique(Graph.Data(:,1:2)); %TotalPasses = zeros(GraphCountNumberOfNodes(Graph),GraphCountNumberOfNodes(Graph)); Betweenness = zeros(GraphCountNumberOfNodes(Graph),1); for Node = Nodes(:).'
