| Abstract(J) | 車両周りの空気流動はその車両性能に大きな影響を与えるため，シャシダイナモメータでは実路走行における空気流動を再現する必要がある．本研究では，車両周りの空気流速の同時多点計測により，実路走行とシャシダイナモメータにおける空気流動の比較を行うとともに，CFDによりこれらの空気流動の差異の要因を解析した． Translation |
| Abstract(E) | Since airflow around a vehicle significantly affects its performance, chassis dynamometers need to reproduce airflow during on-road driving. In this study, airflow on a chassis dynamometer was compared with that during on-road driving by simultaneously measuring airflow velocity at multiple points around the vehicle. In addition, the factors causing the differences in these airflows were analyzed using CFD. |
