Abstract

The present study simulates a practical system such as a silencer. A conventional muffler used in vibratory rollers is usually designed based on experience and its performance could be enhanced in a large degree through structure optimization. In this work modal analysis is done for mode shape finding for existing silencer. It is done to distinguish it from the working frequency to avoid resonating condition. The dimensions of the existing model of the silencer will be referred as benchmarking dimensions to create modified model. Frequency response analysis is carried out to study behaviour of silencer at different frequencies and free free analysis is done with the help of ANSYS 16.0.
