摘要
详细地介绍了经验模态分解方法EMD和算法。对滤波与未滤波的本征模函数（IMF）图做了比较。比较结果说明用滤波后的经验模态分解方法对旋转机械的振动信号波动组分分析比未滤波的有效。
Giving a detail explanation of experimental mode decomposition (EMD) and algorithm we make a comparison of Intrinsic Mode Function (IMF)figue between the filtered and un-filtered. The result of comparison Shows that it is more effective using the filtered EMD to analyze the vibration signal motion composition of rotation machinery than the un-filtered one.
