VibraQuest -> Rotating Machinery Diagnosis

Rotating machinery produces vibration signatures depending upon the mechanism involved. The purpose of analysis is to identify the forcing frequencies so that root cause can be addressed and corrective action can be taken. The Rotating Machinery Module for VibraQuest has built-in template for calculating fault frequencies associated with gearboxes, belt drives, pumps, fans, and other user-defined mechanical components. This module includes an extensive database of over 25,000 bearings from major manufacturers for calculating bearing faults. You can also apply several advanced signal processing techniques for analysis and diagnosis.

Features
  • Automatic machine fault frequency identification and spectrum mapping
  • Choice of bearing, gearbox, belt, fan, pump, and user-defined frequencies
  • Built-in template for calculating fault frequencies caused by various sources
  • Illustrated explanation of selected frequencies
  • Ultra-high resolution with up to 100,000 line FFT
  • Database of over 25,000 bearings from major manufacturers
  • Designed for all four types of bearing faults for any particular bearing: BPFO, BPFI, BFF, and FTF
  • Available gearbox types: two-element, four-element, epicyclic gearbox (with Planetary, Star, and Solar configuration)
  • Enveloping function for fault detection of rolling element and gearbox
  • Cepstrum function for gearbox analysis

 

Rolling element bearing frequencies are specified from item loaded from database.
