Abstract(J)電気粘性流体(ERF)は,電圧の印加で可逆的に粘性が変化する.その特性を利用した制御サスペンションが提唱されており,主流であるバルブ駆動より早く減衰特性を制御できるため乗り心地に優れるとされる.本発表では,ポリウレタン粒子とシリコーンオイルからなるERFの特性とERダンパの減衰特性を報告する.

Translation

Abstract(E)Electrorheological fluid (ERF) reversibly changes its viscosity through applied voltage. A semi-active suspension utilizing the ERF has been proposed. The suspension realize more comfortable to ride than the mainstream valve-driven type one because it can quickly control the damping force. In this report, we will discribe the propreties of ERF composed of silicone oil and polyurethane particles and evaluation results of ER damper.

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.
