The purpose of this experiment was to
conduct design and free free analysis of muffler
system in order to determine the resonant
frequencies of the system and suggest changes in
the system design. For this analysis, Nastran
software was used, In order to determine the
resonance frequencies, were then compiled to
determine which peaks were the most significant
for the system. From the data, side baffles were
selected as weak parts of the muffler. In order to
minimize the effects of these resonance
frequencies, the suggested design improvement is
to add thickness and also add damping to the
system.
Further work has to be done to include the
effects of a mean flow in the experimental set up
and, additionally, the inclusion of higher order
modes in the transfer matrices, which should
increase the frequency range in which the predicted
values would be reliable.
