Abstract
This paper presents the structure optimization of a section muffler,in order to meet the design requirements and standards for a muffler. Based on GT-power software,a series of optimization analysis of the muffler is carried out. Seven candidate schemes are chosen to be compared. Combined with customer requirements,this paper set weight of every optimizing target. Using the evaluation function and DoE (Design of experiments) process, the first optimization scheme is finally determined. It is shown that the total noise of the tail pipe and the second-order noise have a more pronounced decline based on the experimental data, which indicates that the design method brings with a larger upgrade in acoustic performance of muffler.关键词
