Abstract(J)	側面衝突時の乗員傷害低減のために、Bピラーとドアビームについて荷重勾配を向上させる新構造を提案した。それぞれの単体試験を実施し、新構造の効果を確認した。新構造を搭載した車両のCAEモデルでシミュレーションを実施した結果、ダミーの加速度は56%低減し、新構造によって乗員傷害が低減する予測結果を得た。 Translation
Abstract(E)	We developed the body structure technology to reduce occupant injuries. We proposed new structures to enhance the load gradient of the B-pillar and door beams. Test specimens of the door beam and B-pillar were fabricated, and the effect of enhancing the load gradient was verified by single unit tests. Full-car simulation with new structures showed that the load gradient of the car body was enhanced by 4.5 times compared to the conventional structure. The dummy acceleration was reduced by 56%, suggesting that the new structure can reduce occupant injuries.

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".
