Abstract(J)本論文は、ボア変形の摺動方向の分布に対するピストンリングの追従性限界の推定式を提案する。また、前報で開発したリング-ボアの動的接触解析プログラムを用いて、いくつかの簡単なボア変形に対するリングの動的挙動を解析し、提案式と解析結果を比較することによりその妥当性を示す。

Abstract(E)A previous study reported that in a cylinder with a barrel-shaped bore deformation, the piston ring leaves the sliding surface of the bore in the high rotation range. In this paper, the jumping behavior of the rings is discussed in detail, and an estimation formula for the conformability of piston rings to follow the sliding direction is proposed. In addition, the dynamic behaviors of a ring for some simple bore deformations are analyzed using the program for ring-bore dynamic contact analysis developed in the previous paper. By comparing the proposed formula with the analysis results, the validity of the proposed formula is discussed.

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.
