ISO 13373-2:2016推荐了处理和呈现振动数据以及分析振动特征的程序，以监测旋转机械的振动状况，并在适当时进行诊断。针对不同的应用描述了不同的技术。包括用于研究特定机器动态现象的信号增强技术和分析方法。其中许多技术可以应用于其他类型的机器，包括往复式机器。还给出了通常为评估和诊断目的绘制的参数的示例格式。 在分析振动信号时，ISO 13373-2:2016基本上分为两种基本方法: 时域和频域。还介绍了通过改变操作条件来改善诊断结果的一些方法。 ISO 13373-2:2016仅包括机器振动状态监测、分析和诊断最常用的技术。有许多其他技术用于确定机器的行为，这些技术适用于更深入的振动分析和诊断调查，而非机器状态监测的正常后续工作。这些技术的详细说明不在ISO 13373-2:2016的范围内，但第5条中列出了一些更先进的特殊用途技术，以获取更多信息。 对于特定的机器类型和尺寸，ISO 7919和ISO 10816系列为状态监测宽带振动量级的应用提供了指导，VDI 3839等其他文件提供了有关机器特定问题的附加信息，这些问题可在进行振动诊断时检测到。

ISO 13373-2:2016 recommends procedures for processing and presenting vibration data and analyzing vibration signatures for the purpose of monitoring the vibration condition of rotating machinery, and performing diagnostics as appropriate. Different techniques are described for different applications. Signal enhancement techniques and analysis methods used for the investigation of particular machine dynamic phenomena are included. Many of these techniques can be applied to other machine types, including reciprocating machines. Example formats for the parameters that are commonly plotted for evaluation and diagnostic purposes are also given. ISO 13373-2:2016 is divided essentially into two basic approaches when analysing vibration signals: the time domain and the frequency domain. Some approaches to the refinement of diagnostic results, by changing the operational conditions, are also covered. ISO 13373-2:2016 includes only the most commonly used techniques for the vibration condition monitoring, analysis and diagnostics of machines. There are many other techniques used to determine the behaviour of machines that apply to more in？depth vibration analysis and diagnostic investigations beyond the normal follow？on to machinery condition monitoring. A detailed description of these techniques is beyond the scope of ISO 13373-2:2016, but some of these more advanced special purpose techniques are listed in Clause 5 for additional information. For specific machine types and sizes, the ISO 7919 and ISO 10816 series provide guidance for the application of broadband vibration magnitudes for condition monitoring, and other documents such as VDI 3839 provide additional information about machinery？specific problems that can be detected when conducting vibration diagnostics.
