| Abstract(J) | 実車用風洞や高速度カメラを使わずに，次の現象を路上走行中に撮影する手法を開発した．1）車体周囲の空気流，2）車輪開口部を通る空気流，3）転動中のタイヤ変形，4）車両表面騒音源の強度分布．使用機器はa）道路の横や溝底に設置した鏡，b）車体と車輪に固定した静止画用カメラと音響カメラである． Translation |
| Abstract(E) | We have developed a method for observing and photographing the following phenomena while driving on the road without using a large wind tunnel or high-speed cameras. They are 1) airflow around a vehicle body, 2) air flowing through wheel openings, 3) deformation of rolling tires and 4) intensity distribution of noise sources on a vehicle surface. The tools used are a) a mirror installed along the roadside or on the bottom of a pit that dug down the road and b) a still image camera and an acoustic camera fixed on the vehicle body or on the rotating wheels. |
