Design & Optimization Of Exhaust Muffler & Design Validation
For an automotive exhaust system the noise level, transmission loss & back pressure are the most important
parameters for the driver & engine performance. In order to improve the design efficiency of muffler, resonating of the
exhaust muffler should be avoided by its natural frequency. Mufflers are most important part of the engine system and it is
commonly used in the exhaust system to minimize the sound transmission level which is caused by exhaust gases. The design
of muffler becomes more and more important for noise reduction. The solid modeling of exhaust muffler is created by
CATIA-V5 and modal analysis is carried out by ANSYS to study the vibration and natural frequency of muffler. So as to
differentiate between the working frequency from natural frequency and avoid resonating..
