| 摘 要： | 主成分是通过把原来多个变量转化为少数几个互不相关的主成分的一种统计方法,最终达到数据化简、揭示变量间的关系和进行数据解释的目的.通过实船航行试验,证明了主成分分析可以在信息损失较少的前提下提取振动噪声源之间存在的耦合信息.

| Abstract: | The main vibration signals can be obtained by reducing its dimensions through matrix conversion using in the principal component analysis,so that the analysis to the coupling information for vibration noise source can be realized.Taking an example of the naval ships test,it demonstrates that the principle component analysis can obtain information almost any loss,and it is a convenient way to extract the coupling information between the vibration noise sources. |
