Abstract(J)	自動車の走行抵抗を低減するため，タイヤのトレッドパターンの違いが空気抵抗に与える影響を調べた．CFDによる検討には2種類の車両を用い，トレッドパターンの違いによりタイヤ4本分でタイヤのCD寄与が最大0.003変化することが分かった．また，トレッドパターンの違いが車両背面流れにも影響することが分かった． Translation
Abstract(E)	To reduce vehicle running resistance, the effect of differences in tire tread patterns on aerodynamic drag was investigated. Using two types of vehicles for CFD analysis, it was found that variations in tread patterns can change the tire drag contribution (CD) by up to 0.003 for all four tires combined. Additionally, differences in tread patterns were found to influence the flow field behind the vehicle.

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
