| Abstract(J) | 四輪車から発生する風騒音は，乗員を不快にさせる要因の一つであり，中でも笛吹き音のような耳障りな音は品質問題となる．フィン形状のフロントグリルから発生した笛吹き音について，フィン周りの流れと音の関係を明らかにするため，煙とレーザーを用いた可視化を行い，渦構造を観察した． Translation |
| Abstract(E) | The wind noise generated from vehicles is one of the major noise source to make passengers revolted, and a jarring noise like a whistle especially becomes a quality problem. To clarify the relationship between the flow around the fin and the whistle noise generated from the fin-type front grille, flow visualization were carried out. As a result, the strong vorticity can be seen behind the front grille. Clarification of the phenomenon of whistle noise generated from a fin-type front grille. |
