| Summary: | This work deals with the problem of vibratory energy flow
from the internal electrical motor-compressor assembly (kit) to the shell of a
hermetic compressor. The theoretical model is based on Statistical Energy
Analysis. Shell and body vibratory energies have been measured at a standard
operation condition, and the coupling loss factor thus obtained agreed well with
predicted values calculated from impedance data. Several parameters, such as
body and shell impedance, spring and shell loss factor, and model of the spring
(tension and compression) were varied and their effects upon the compressor
noise analyzed. Good agreement between theoretical and experimental results was
observed. |
