| Abstract(J) | 地面移動とホイール回転が動的空気力に及ぼす影響を明らかにするため、ハッチバック車模型のピッチ運動を対象に、風洞計測とCFD解析を行った。解析の結果，地面移動とホイール回転により、模型床下、リヤホイールハウスの流れ場が変化することで、模型に作用する動的空力特性が変化することを明らかにした。 Translation |
| Abstract(E) | The effect of a moving ground and rotating wheels on transient aerodynamic loads acting on a hatchback car model in pitching motion were investigated by dynamic wind tunnel tests. The results showed that phase differences of the lift force and the pitching moment became smaller with respect to the pitch angle of the model, and the gain of the lift force became larger with the moving ground and rotating wheels. CFD results revealed that these changes in transient aerodynamic characteristics could be attributed to changes in flow fields under the center floor and the rear wheelhouses. |
