Abstract(J)車両に路面と接する部分はタイヤのトレッド部分のみである。タイヤトレッドと路面の間で起こる摩擦はタイヤの安全面でも機能面でも極めて重要である。本稿では、ゴム摩擦機構、摩擦円、ウェットグリップ、氷上路でのグリップなどについて説明する。さらに、粘着摩擦、変形損失摩擦の違い及びスリップ速度、温度、ゴム配合等の影響についても述べる。そして、タイヤと路面間の摩擦を増やす方法の幾つかの提案も紹介する。

Abstract(E)The only part of a vehicle that contacts the road surface is the tire tread. Friction between tire tread and road surface is critical for safety and functionality. This paper will give an overview of Rubber friction mechanism, Tire friction circle, and the effects of wet or ice surfaces on tire friction. In addition to this, the relationship between surface adhesion, hysteresis, slip speed, temperature, rubber compound and other influential attributes will be mentioned. And some proposals of the methods for increasing tire friction will also be introduced.

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.
