Design and Optimization of Muffler Guard Using Modal Analysis

B. Hareesh, A. Vidyasagar


Mufflers are important part of engine system and commonly used in exhaust system to minimize sound transmissions caused by exhaust gases. Design of mufflers is a complex function that affects noise characteristics, emission and fuel efficiency of engine. Therefore muffler design becomes more and more important for noise reduction.

The noise control is depends upon types of louvered holes appeared on muffler. This project mainly focused on reducing the noise from muffler by developing new type of louvered holes with proper material. 

This project deals with design of Louvered muffler guards using Unigraphics software and modal analysis of mufflers done to find natural frequencies and deformations induced in muffler these analyses are done in Ansys simulation tool with different material properties are studied in this project.
