To minimize unwanted noise, the exhaust gas of high pressure and high temperature coming out of internal
combustion engine passes through silencer. Various types of silencers like absorptive, reactive and resonating,
perforated type are widely implemented in actual practice .perforated reactive mufflers have an effective
damping capability. This paper deals with comparative structural analysis of such automobile silencer of both
perforated and non-perforated one. Here, geometrical model of perforated and non-perforated silencers has
been designed. The analysis of the models for the deformation, stress and strain the were analyzed using ANSYS
WORKBENCH 14.0. Boundary Element Method had been adopted for the design analysis for a comprehensive
comparative analysis on silencers of perforated and as well as non-perforated type.
