| Abstract(J) | 現在の風洞試験では，形状変更と空力値測定を交互に繰り返し，目標性能を満たす形状の探索を行っている．遠隔操作で形状変更する装置を車両に搭載し，形状変更のために風路に人や必要機材が入ることなく作業が出来れば，試験は風を止めることなく連続的に行うことが可能となる．これにより限られた時間内での試験数を増加させ，目標性能達成の確度を上げることができる．本研究では，遠隔操作が可能なFRストレイキとRRスポイラの形状可変装置を開発した．モックアップに搭載し風洞により動作確認を行い，従来と同時間内で10倍の試験数に増加できることを確認した． Translation |
| Abstract(E) | Wind tunnel tests are conducted by repeatedly changing the shape and measuring the aerodynamics to search for automobile shapes that meet the target performance. If active aero devices with shapes changed by remote control could be mounted on automobiles to allow work to be performed without entering or moving equipment into the wind path to change the shape, this will enable continuous and efficient testing without stopping the wind, thereby increasing the number of tests within a limited development period and raising the probability of attaining the target performance. This research developed active devices for the front strakes and rear spoiler that can be controlled remotely, mounted them on a mock-up, and confirmed operation in wind tunnel tests. The results confirmed that the number of tests can be increased to 10 times the previous number within the same period of time. |
