振动数据处理中分辨率的确定方法及应用

在振动数据的处理过程中,需要对振动数据进行频谱分析,分辨率选择的好坏将直接影响到分析结果。分辨率的选择并非越高越好,应根据试验结果进行选择。选择与试验结果匹配的分辨率非常重要,如果数据处理分辨率选择不当,处理结果有可能误差比较大甚至错误,此外当分辨率无法改变时还可以根据分辨率选择数据段,以保证处理结果的准确性。本文根据工程实验总结出了振动数据频谱分析过程中分辨率的选择以及试验数据段选取的方法,在处理振动数据中验证了其正确性。

Calculation Method and Application of Resolution in Vibration Data Processing

In vibration data processing,the choose o f resolution will influence the result of spectrum analysis.Choose high resolution is not always proper,we choose resolution based on experiment result will lead to a better result.If choose the improper resolution,processing result maybe wrong or produce big errors.Besides,when resolution could not be changed,we can choose data that we will process based on resolution in order to make sure the veracity of the result.This article summarized the choose method of reso...
