Abstract(J)	エンジン軸受の摩擦損失低減について，油膜内のせん断応力に着目し，新たに設計した試験装置を用いて実験的に評価した．得られた知見から，ベアリング表面特性の最適化が流体潤滑領域での摩擦損失低減に有効であることを示した． Translation
Abstract(E)	Friction loss reduction in engine bearings was investigated by focusing on oil film shear stress. Experiments were conducted using a newly designed test rig. The results indicate that optimization of bearing surface properties is effective in reducing friction loss under hydrodynamic lubrication conditions.

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".
