What is harmonic in SAP PM-PDM-VA - Vibration Analysis?

SAP Term: harmonic

• Component: PM-PDM-VA

• Component Name: Vibration Analysis

• Description: A spectral peak at a frequency that is a whole number multiple of the fundamental frequency, or of the frequency of any excitation force present. A harmonic of a frequency 'n' times that of the fundamental frequency is called 'nX'.

• Key Concepts: 
  Harmonic is a term used in the SAP PM-PDM-VA Vibration Analysis component. It is a type of vibration that occurs at a specific frequency and is caused by an imbalance in the rotating parts of a machine. Harmonic vibrations can cause damage to the machine and its components, so it is important to identify and address them. 
  
  How to use it: 
  In SAP PM-PDM-VA Vibration Analysis, harmonic vibrations can be identified by analyzing the vibration data collected from the machine. The data can be analyzed using various techniques such as Fourier analysis, which can identify the frequency of the harmonic vibration. Once identified, corrective action can be taken to reduce or eliminate the harmonic vibration. 
  
  Tips & Tricks: 
  It is important to regularly monitor machines for harmonic vibrations, as they can cause damage over time. Additionally, it is important to ensure that all rotating parts are properly balanced and aligned to reduce the risk of harmonic vibrations. 
  
  Related Information: 
  Harmonic vibrations are just one type of vibration that can occur in machines. Other types of vibrations include random, transient, and continuous vibrations. It is important to understand the different types of vibrations and how they can affect machines in order to properly diagnose and address them.
