摘要
机械振动信号反映了机械系统工作过程中的内在状态,振动信号承载着机械系统工作状态的重要信息.介绍了机械振动信号描述的两类方法,并对振动信号的常用分析方法加以阐述,为机械系统振动信号的分析提供指导.
Mechanical vibration signal reflects the inner status of mechanical system. The vibration signals carry on the important information of the systematical working states. This essay introduces two methods of the mechanical vibration signals, and some cementation on several methods is presented which are able to guide on the mechanical vibration analysis.
