代码说明:

  测量6205深沟球轴承的故障振动加速度信号, 对信号进行时频分析, 利用经验模态分解方法将振动信号分解成不同特征时间尺度的固有模态函数,对每个固有模态函数进行Hilbert 变换得到Hilbert 谱,通过谱分析识别轴承的故障部位和类型, 证实Hilbert 谱的有效性(Measuring 6205 deep groove ball bearing fault vibration acceleration signal, the signal frequency analysis, empirical mode decomposition method to decompose the vibration signal into different characteristic time scales of intrinsic mode functions, the Hilbert transform of each intrinsic mode functions Hilbert spectrum, spectral analysis to identify the location and type of bearing failure, confirmed the effectiveness of the Hilbert spectrum)

    MATLAB连续潮流程序(9节点) (百度百科)连续潮流需要注意的问题: 1 连续潮流中两个重要的问题是:连续参数的选择和步长的确定。参数选取不正确或是步长不合理都会导致潮流不收敛。 2 连续潮流所求出的负荷裕度是针对特定网络状态和特定的负荷增长方式而言的。当增长方式改变或是网络结构或是参数发生改变后,连续潮流求出的负荷裕度是会改变的。 3 至今为止,出现了基于负荷增长的连续潮流、基于网络断线故障的连续潮流等。 (MATLAB continuous flow program (9 nodes) (Baidu Encyclopedia) continuous flow problems that need attention: A continuous trend in two important questions are: selection and step continuous parameter determining long. Parameter selection is incorrect or unreasonable step will not lead to the convergence trend. 2 continuous load margin is determined by the trend for a particular network status and specific in terms of load growth. When changing the growth mode or network structure or parameters are changed, the load margin is calculated continuous trend will change. 3 So far, there has been a continuous trend based on load growth, based on network fault and continuous flow and so on.)
