Title: | Sub-chamber optimization for silencer design | Authors: | Yu, X Tong, Y Pan, J Cheng, L |
Issue Date: | 1-Sep-2015 | Source: | Journal of sound and vibration, 1 Sept. 2015, v. 351, p. 57-67 | Abstract: | This study proposes sub-chamber optimization for the design of a silencer. A theoretical basis is presented for a description of the overall transmission loss (TL) of the silencer, using the TLs of each of the cascade-connected multiple sub-chambers and the interactions between them. Three typical sub-chamber configurations are considered, representing the effects of varying geometrical parameters, adding internal partitions, and introducing perforated liners. The characteristics of the sub-chambers, influences of the parameters, and the limits of design are investigated to provide guidelines for optimization. It is demonstrated that, by connecting sub-chambers with optimized TLs to tackle different frequency regions, a desired broadband attenuation performance can be achieved. The proposed design scheme with sub-chamber optimization greatly reduces the design variables and calculation costs compared with global optimization, thus offering wider scope in silencer design. | Publisher: | Academic Press | Journal: | Journal of sound and vibration | ISSN: | 0022-460X | EISSN: | 1095-8568 | DOI: | 10.1016/j.jsv.2015.04.022 | Rights: | © 2015 Elsevier Ltd.
