一、概述所谓振动诊断就是通过对机器振动特性的测量来检查机器的机械完整性。它可以是对运行中的机器进行测量,也可以是对非工作状态的机器进行人工激振测量。通过对实测数据的分析比较,来判断机器的完好程度,查找故障根源。南于许多机器故障都是因整机或局部振动过大,从而产生附加冲击或导致振动频谱结构发生变化的,因此就能 First, an overview of the so-called vibration diagnosis is to measure the vibration characteristics of the machine to check the mechanical integrity of the machine. It can be measured on the running machine, but also on the non-working machine for manual vibration measurement. Through the analysis and comparison of the measured data to determine the integrity of the machine to find the root cause of the malfunction. Many machine faults in the South are caused by excessive vibrations of the whole machine or parts, resulting in additional shocks or changes in the structure of the vibration spectrum,
