Özet:

 


Diesel generators are one of the most
common used energy sources for maintaining the continuity of electrical energy.
Diesel generators cause high noises during their operation. There are many
methods of eliminating the noise problems that diesel generators generate
during energy production. However, these methods show differences according to
the type of noise source. In this study, the problem of noise was emphasized
that it is caused by structural vibrations of diesel generators. Therefore, the
method of coherence function, which is an analytical method, was used for the
detection of noise caused by structural vibrations. A test software and user
interface was developed to perform sound and vibration measurement and analysis
with using coherence function. The coherence analysis of sound and vibration
data was made by performing various tests and measurements with the developed
test software. In the coherence tests of diesel generator, the vibration
frequencies that cause high noise at the measurement points were determined. In
order to verify the coherence tests, the computer-aided 3D solid model of
diesel generator used in the tests was created. Computer-aided modal analysis
of the diesel generator was performed by using this model. The modal analysis
was performed at the vibration measurement points and the frequencies that
cause high noise. Coherence test results and modal analysis results were
compared. It was seen that the results of the coherence measurement and the
results of the computer-aided modal analysis supported each other. As a result
of these studies, it was shown by computer-aided modal analysis that the high
noise occurring in diesel generators can be determined by the coherence tests.
