Abstract(J)電界の印加により流体の粘度を直接制御可能な電気粘性流体(ERF)を用いて,機械的制御バルブによらない滑らかな可変減衰力での乗り心地向上を目指したERセミアクティブサスペンションシステムを開発した.今回開発したシステム及びERダンパの構成,並びに実走行試験による乗り心地評価結果を報告する.

Translation

Abstract(E)To achieve smooth ride comfort and seamless switching of variable damping force without having mechanical control valve, we have developed ER semi-active suspension system realized by Electrorheological(ER) fluid whose viscosity can be controlled directly through applied voltage. In this report, we will describe our system layout, structure of the ER damper and result of ride evaluation by actual vehicle.

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.
