Noise and vibration characterization and statistical energy analysis of a scroll compressor.

Author(s) : ROCKWOOD W. B.

Summary

Statistical energy analysis (SEA) is used to diagnose the operational dynamic characteristics of a scroll compressor. The SEA model is benchmarked against test data for external force as well as internal pressure pulsation excitation (with air). Sound power contributions from various regions of the operating compressor are determined by extrapolation of measured surface vibration levels. These results are compared with SEA predictions for internal force and pressure pulsation excitation sources. The distinct characteristics of the two sources, revealed by the SEA model, help separate them in the operating machine and help for design modifications.
