Abstract(J)重量車の空力性能向上は燃費の改善に大きく寄与する.そこで,本研究ではトラックのキャブ形状に着目し,ボンネット高さやフロントウィンド傾斜角等をパラメータとして,大幅に空力性能を改善し得る概形モデルを作成した上で,遺伝的アルゴリズムを用いた多目的最適化手法により,より詳細な形状の最適化を行なった.

Translation

Abstract(E)Improvement of aerodynamic performance of heavy-duty vehicles greatly contributes to improvement of fuel consumption. In this study, focusing on the cab shape of a truck, a rough shape model which could drastically improve aerodynamic performance was made by using bonnet height, front wind tilt angle, etc. as parameters, and more detailed shape was optimized by a multi-objective optimization method using a genetic algorithm.

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.
