特征分析是一种识别旋转机械和结构全部振动特性的有效方法,它亦可用于机械故障诊断,振动监测等方面。本文先介绍特征分析的内容及基本关系,再介绍利用一台原没有特征分析功能的通用实时分析装置,经过扩展功能,达到对旋转机械如柴油机,电机等作特征分析的测量和分析的目的。同时亦考核了所添加的软硬件功能,获得了所需的全部特征分析的谱图,得到了所测机械韵详细的振动情况,文章对测试及分析结果作出说明,指出进一步的工作。

Characteristic analysis is an effective method to identify all the vibration characteristics of rotating machinery and structures. It can also be used in mechanical fault diagnosis and vibration monitoring. This paper first introduces the content and basic relationship of feature analysis, and then introduces the use of a generic real-time analysis device without original feature analysis function to extend the function to achieve the purpose of measuring and analyzing the characteristics of rotating machinery such as diesel engines and motors. At the same time, the software and hardware functions added were tested, the spectrum of all the required features was obtained, and the detailed vibration of the mechanical rhyme was obtained. The paper described the testing and analysis results and pointed out further work.
