Abstract(J)ドライブトレイン冷却性能評価のためのCAE手法を開発し、内部油流れに基づいたユニットの三次元熱伝達の予測を可能にした。これにより、ユニット温度分布を可視化し、ユニット形状の冷却性能への寄与度が解析可能となった。本手法をディファレンシャルユニットへ適用し、効率的な冷却フィン配置の検討を実施した。

Translation

Abstract(E)The CAE method was developed for the evaluation of the drivetrain cooling capability. The prediction of the three-dimensional heat transmission of the unit based on the internal oil flow was enabled. As a result, distribution of the temperature of the unit was made visible, and it became possible to analyze the effect to the cooling capability of the unit shape. This method was applied to differential unit, and an efficient geometry of the fin was examined.

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.
