Abstract(J)自動車用ディスクブレーキにおいて,高速制動時にHot Spotと呼ばれる熱の縞模様が発生し,これに起因してHot Judderと呼ばれる振動が車両に生じる.著者らは,本現象の発生メカニズム解明を目的としてダイナモ試験機による実験的検証を行い縞模様は発生と減衰を繰り返し,時間経過とともに数が増加することを明らかにした.

Translation

Abstract(E)In automotive disc brakes, a pattern of heat known as a hot spot forms during high-speed braking, causing a vibration known as hot judder in the vehicle. To clarify the mechanism behind this phenomenon, the authors conducted experimental tests using a dynamometer, clarifying that the pattern repeatedly forms and dissipates, and that the number of such patterns increases over time.

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.
