摘要
运用主成分分析方法,经过矩阵变换,提取振动信号的主要信息,从而实现对振动噪声源的分析。通过对100CLG-30船用立式单级离心泵试验数据的分析处理说明,在有用信息量损失较少的前提下,该方法可以提炼运转状态信息,是一种解决高维复杂系统状态分析问题的简便有效的统计方法。
The main vibration signals can be obtained by reducing its dimensions through matrix conversion in the principal component analyzed, and realize the analysis to the vibration noise source. Taking an example of an analysis of the resuits of test for 100CLG-30 marine vertical centrifugal pumps, this paper demonstrates that the principal component analysis can obtain information almost without any loss, and it is an effective and convenient way to analyze the status of complex multi-dimensional system.
