What is 'amplitude reduction factor' in SAP PM-PDM-VA - Vibration Analysis?

amplitude reduction factor - Overview

• Component: PM-PDM-VA

• Component Name: Vibration Analysis

• Description: The percentage by which the amplitude must be reduced for higher harmonics of a vibration source, for example, if amplitude at 1X is 2 mg, the amplitudes at 6X, 7X, and 8X are reduced by 50% for efficient calculation.

  Key Concepts: 
  Amplitude Reduction Factor (ARF) is a parameter used in the Vibration Analysis component of SAP's Plant Maintenance and Plant Design Management (PM-PDM-VA) module. ARF is used to reduce the amplitude of vibration signals in order to make them easier to analyze. It is calculated by dividing the peak amplitude of a signal by its RMS (root mean square) value. 
  
  How to use it: 
  ARF can be used to identify the severity of a vibration problem. A higher ARF value indicates that the vibration signal has a higher peak amplitude than its RMS value, which means that the vibration is more severe. Conversely, a lower ARF value indicates that the vibration signal has a lower peak amplitude than its RMS value, which means that the vibration is less severe. 
  
  Tips & Tricks: 
  When using ARF, it is important to remember that it is only an indicator of the severity of a vibration problem and not an absolute measure. It should be used in conjunction with other parameters such as frequency and acceleration to get a more accurate picture of the problem.
