轴承振动的傅立叶级数法分析

Analysis with Fourier Progression method for bearing vibration

利用傅立叶级数,将轴承零件几何偏差分解成各次谐波,进而分析振动响应,分析结果表明,并非零件几何偏差的各次谐波都引起轴承振动。参考文献4篇。

Using pourier Progression method, the geometric Variation of bearing parts can be resolved into various order harmonic waves, and then to analyze the vibration response. The result of analysis shows, it is not all of the various order harmonic waves of the geometric variation of bearing parts can lead to bearing vibration.
