Muffler Analysis Associated with the Porosity Changes of the Perforated Plate
- 발행 : 2014.10.29
초록
By this time, the study of mufflers has been progressed a lot. However, we don't have enough information about what some factors in muffler have an influence on transmission loss. So, we examined the tendency of the transmission loss depending on the porosity of perforated plates. We tested mufflers currently in use and changed porosity of perforated plates in mufflers to find out tendency of the transmission loss. As a result, the tendency of the transmission loss was shown differently depending on the position of perforated plate.
