| Abstract(J) | 騒音対策諸元設計に際し、インドアパスバイ計測での寄与度解析を活用することで、効率よく各部品寄与を明確化し、開発期間短縮が図れる。実験寄与度解析の音源にCAE解析による変更を加えることで、試作部品を作らずに騒音値を予測する手法を提案する。本手法をマフラ内部構造の変更に適用し、実測との妥当性を明らかにした。 Translation |
| Abstract(E) | Contribution analysis combined with indoor pass-by measurement can identify each component contribution and reduce development time. We introduce a method to estimate the pass-by noise level without having actual component installed, applying modification calculated with CAE analysis to measured noise source. Application example of the method on change in muffler structure will be presented. |
