Vibration Field Testing for Compressor

As part of design validation of a compressor device, vibration measurement was carried out to verify the vibration levels in various locations inside the compressor and to check the field failure of a chiller compressor at the low frequency condition. 

Our approach included:

- Identifying 27 critical locations with severe vibration levels

- All 27 measurement locations were covered using seven tri-axial accelerometers with four sets of measurements and repeating sequence.

- A dampened model was proposed post which the vibration level was reduced within the limits for the improved design.

- CAE results were compared with the old and dampened model.

- The measurements were benchmarked with the data of the old system to study improvements.
