Vibration Analysis

Our vibration analysts are prepared to travel worldwide to measure vibration and perform vibration analysis on machines and/or structures. We perform acceptance testing, startup vibration measurements, troubleshooting analysis, and routine machine health monitoring. In addition, we perform force-response measurements for frequency-response functions, transmissibility, accelerance, mobility, and dynamic stiffness as well as their reciprocals. We use the following instruments:

  • DI-2200 Realtime FFT Analyzers, 2-channel
  • HP 3560A Dynamic Signal Analyzer, 2-channel
  • Zonic A&D 3522 FFT Analyzer
  • Zonic A&D 3525 Dual Channel FFT Analyzer
  • Genrad Sound Level Meters
 
  • Wilcoxon General Purpose Accelerometers
  • PCB General Purpose Accelerometers
  • PCB 393C Seismic Accelerometer
  • Wilcoxon 731 Seismic Accelerometers
  • Vibra-Metrics 1030 Seismic Accelerometers
  • Proximity Probes, Bently-Nevada
  • Bently-Nevada Velocity Transducers
  • Kaman Proximity Probes
  • Strain Gages
  • Pressure Transducers
  • Instrumented Force Hammers

 
  In addition to short-term vibration analysis, we can instrument and record dynamic signals over long periods of time. This is routinely done to monitor construction activity in sensitive areas or to understand physical processes over time. Our recording instrumentation includes the following:
 
  • Gould Windograf 4-channel Chart Recorders
  • Gould Easygraf TA 240 2-channel Chart Recorders
  • TEAC RD 180T PCM Data Recorder, 8-channel
  • TEAC RD 111T PCM Data Recorder, 8-channel
