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.

About search


How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
