Abstract(J)	ブレーキ鳴きの抑制には，予測技術の確立が不可欠である．本研究では，ディスクブレーキ模擬装置を用いた実験，及び低自由度モデル上の複素固有値解析から鳴き発生のメカニズムを検討している．本報告では，ディスクロータ・パッド間の摩擦力を要因とするエネルギ流入が確認され，パッドが自励振動に至ることを確認した． Translation
Abstract(E)	An establishment of a prediction technology is essential for the reduction of brake squeal. In this study, a mechanism of brake squeal generation is investigated by experiments using a simplified disc brake system and simulation on a complex eigenvalue analysis with low-degree-of-freedom model. This report revealed the energy inflow is caused by the frictional force between the disc rotor and pad, and led to self-excited vibration of the pad.

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".
