| Abstract(J) | 運動性能向上を狙った空力デバイスの効果は定常空気力だけでは説明できず，運動で発生する動的空気力に着目することが必要と考え，実車風洞内で加振試験を行なった．走行風によりフロントは動きにくくリヤは動きやすくなり，流れが乱れると動きにくく整流すると動きやすくなる等，動的空気力の影響が確認できた． Translation |
| Abstract(E) | To investigate the effects of aerodynamic devices aimed at improving vehicle dynamic performance, we focused on dynamic aerodynamic forces generated by vehicle motion rather than relying solely on steady aerodynamic forces. Full-scale excitation tests were conducted in a wind tunnel using a vehicle. The results showed that the oncoming flow makes the front of the vehicle less responsive to excitation while making the rear more responsive. In addition, when the flow becomes disturbed, the vehicle tends to move less easily, whereas flow rectification increases its ease of motion. These findings confirm the influence of dynamic aerodynamic forces on vehicle motion. |
