| 摘 要： | 介绍了EMD算法和EMD能量熵理论,并且运用此理论实现了提升机齿轮箱故障诊断。对振动信号进行EMD分解并求出各IMF分量的能量占总能量的百分比,由EMD能量熵的定义求出熵值,根据不同的熵值实现对齿轮箱正常状态和断齿故障的判别。

| Abstract: | The theory of the EMD algorithm and the EMD energy-entropy are introduced.This theory is applied in the hoist gearbox fault diagnosis.It is used to decompose the signal of the vibration of the hoist gearbox run-ups and to calculate the percentage of each IMF component in the total energy.The value of energy-entropy can be calculated according to the definition of EMD energy-entropy.The normal condition and tooth broken fault condition of the gearbox can be discriminated by the different values of energy-entropy. |
