机器的工况监测和诊断.振动条件监测.第2部分:振动数据的处理、分析和表示(ISO 13373-2-2016)

[中文适用范围]： 本部分 ISO 13373 规定了用于处理振动数据、显示振动数据以及分析振动参数以监测旋转机械振动状态和（在可能的情况下）进行故障诊断的推荐方法和程序。其中描述了适用于不同应用的各种技术，包括信号改善技术和分析特定机器振动行为的分析方法。许多这些技术也可用于其他类型的机器，包括具有往复部件的机器。此外，还给出了通常用于评估和诊断的参数输出格式示例。本部分 ISO 13373 分为处理和分析振动信号的两种基本方法：时域和频域。此外，还提供了通过改变运行状态以获得更准确诊断结果的方法。本部分仅涵盖用于机器振动状态监测、振动分析和诊断的最常用技术。还有许多其他技术可用于确定机器状态，并在更深入地进行振动分析和诊断时应用，这超出了本部分 ISO 13373 的应用范围。然而，部分这些高级专门技术在第 5 节“其他技术”中列出以提供进一步信息。对于特殊机器类型和尺寸，ISO 7919 系列和 ISO 10816 系列的规范提供了关于在状态监测中使用宽带振动测量的指导。其他法规，如 VDI 3839 指南，包含有关振动诊断中可能出现特定机器问题的额外信息。 [外文原描述]： 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.
