A Study on the Development of a New Muffler Component required in the Geometrically Constrained Space
제한된 공간에 맞는 새로운 소음기부품의 개발에 대한 연구
Abstract
To get minimum noise level by making full use of the constrained geometric space and being compatible with the minimum pressure-drop condition, 3-pipe through-flow system is designed by inserting a new pipe which is shaped a resonator in the cavity of 2-pipe system. As a result of the 1/3-octave-band frequency analysis for the noise reduction characteristics, this system is proved to have good sound attenuation effect in the high frequency region, so that it is found to be a useful component of a muffler.
