Online Store: Technical Paper - PeakVue™ Description & Applications

Description: 95 page booklet about PeakVue™ - Illustration of its Wide Array of Applications in Fault Detection & Problem Severity Assessment

Part Number PKV-1 (95 page booklet) - $99

    

Highlights:

  • Stress Wave analysis is a powerful complementary tool that can detect a range of faults and problem conditions that Vibration Analysis alone might miss under certain conditions.
  • This publication serves as a “white paper” on the PeakVueTM analysis method which is actually a measure of “stress wave” activity in metallic components that are associated with impact, friction, fatigue cracking, lubrication, etc.
  • They generate faults in various components such as rolling element bearings and gears.
  • When components impact a series of stress waves will be generated that propagate away from the location of the defect in numerous directions.
  • The wave propagation introduces a ripple on the machine surface that causes a response output in a sensor detecting absolute motion such as an accelerometer or a strain gage.

      This paper provides answers to:
      • What are stress waves?
      • How are they measured?
      • What are recommended measurement setups needed to ensure optimum PeakVue data is captured (proper high-pass filter, FMAX, # FFT lines, #time domain samples, etc.)?
      • How to choose the parameters that are dependent on the type of fault for which one is looking (cracked gear tooth versus generalized tooth wear, for example)?
      • How to specify meaningful PeakVue alarm levels to various machine components and operating speeds?
      • How studies have been conducted to determine the effect on PeakVue amplitudes of certain faults occurring on specific components and how they can generate very different amplitudes?
      • How certain faults might actually go undetected if the proper setup parameters are not chosen?
      • How Real World Case Histories are used to demonstrate the stress wave method?
