在现场采录数据似乎是简单的工作,实际上其成功与否尚取决于实际经验。 在振动分析中,频率总是振源特性的关键。振幅表示任意强迫函数的大小。相位、振型,也可以决定振源特性。 测量装置的考虑 轴是否裸露?轴承是置于凹处,联轴器护罩是否必须卸下?能否使用频闪灯进行相位测量?是否有参考定位键槽?装置能够停止重新起动吗?作为相位参考或许能用反映(粘)带。如果采用(粘)带和感光片,是否用磁性夹具或其他工具?如
Data mining on the scene seems to be a simple task, in fact, its success or not depends on the actual experience. In vibration analysis, the frequency is always the key to vibration characteristics. Amplitude means the size of any forcing function. Phase, vibration mode, you can also determine the vibration source characteristics. Is the shaft considered for the measuring device exposed? The bearing is placed in a recess and the coupling guard must be removed? Can phase measurements be made with the strobe light? Is there a reference keyway? Can the unit stop being restarted? Reference may be able to use reflective (sticky) band. If you use (sticky) tape and photosensitive film, whether the use of magnetic fixtures or other tools?
