Abstract(J)従来から車体剛性の操安性能への影響が報告がされてきたが、広域の計測が困難であり、走行中の詳細な車体変形や仕様変更の効果について明らかでない部分が多い。今回、数千点の計測可能な光ファイバ歪センサにより、広域かつ詳細な車体変形の計測を可能にし、補強による走行中の捩り変形低減効果を定量的に明らかにした。

Translation

Abstract(E)Effect of body stiffness for steering stability has been reported. However, it is difficult to measure body deformation over a wide area, there are unclear parts about body deformation and effect of changing stiffness in actual driving condition. In this study, we measured wide area and detailed body deformation using optical fiber strain sensor. And, revealed quantitative reduction effect for torsional deformation by stiffener.

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.
