Abstract(J)自動車の空気抵抗(CD)は,自然風(横風)によりCD は増加傾向となり燃費が悪化する.自然風分析結果から,頻度の高い横風:偏揺角4 度に着目し,偏揺角0 度から4 度の⊿CD 低減について検討している.背面流れの偏向に着目し,セダン車の⊿CD 低減アイテムを検討した結果を報告する.

Abstract(E)Crosswind tends to increase the aerodynamic drag of a vehicle. Based on the analysis of the natural cross wind, 4 degrees of yaw angle is focused as the frequent crosswind. In this report, aerodynamic items on sedan vehicles to reduce CD worsening from 0 to 4 degrees (ΔCD) caused by the inclination of rear wake was studied.

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".
