Abstract(J)	本研究では，リング挙動の予測精度を検証したモデルを用いてピストン2次挙動とリングフラッタの関係を明確化した．さらに，ピストン2次挙動がランド圧に影響を及ぼし，フラッタ発生に寄与することを示した． Translation
Abstract(E)	In this study, the relationship between piston secondary motion and ring flutter was clarified using a model whose prediction accuracy for ring behavior had been validated. Furthermore, it was demonstrated that piston secondary motion affects land pressures and thereby contributes to the onset of flutter.

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".
