柯尔莫哥洛夫熵及其在故障诊断中的应用

Kolmogorov Entropy and Its Application to the Diagnosis of Mechanical Faults

熵作为一个状态函数 ,表征了系统能量在空间分布的均匀程度 ,直接反映了系统的状态。本文详细分析了柯尔莫哥洛夫熵 (Kolmogorov熵 ,简称 K熵 )的物理含义及其从实测的时间序列中计算 K熵数值的算法 ,并首次将 K熵引入大型旋转机械的故障诊断领域中 ,利用

Entropy is a function of state, it represents the measure of uniformity of the distribution of system energy in space. This paper first analyzes the implication of Kolmogorov entropy and the algorithm of calculating Kolmogorov entropy from experimental data,then applies Kolmogorov entropy to the diagnosis of mechanical faults.
