The bend round bar has a curvature R and attack angle α. In the experiment, we investigated the effects of R or α on the aerodynamic sound generated by bend round bars. The results of the frequency analyses of the aerodynamic sounds show that the aeolian tones are generated by the bend round bar, when α is large, but that when α is small, although the aeolian tones are reduced, the broad band noise of lower frequencies are increased. In order to decrease aeolian tones, we find the appropriate attack angle α.}, pages = {G203-1--G203-4}, publisher = {日本機械学会}, title = {円弧状に曲げた丸棒から発生する空力音に関する研究(2)}, volume = {2007}, year = {2007}, yomi = {マツモト, ヒロキ and サイトウ, ケンイチ} }
