Abstract(J)	ステアバイワイヤ車両のロードインフォメーション再現を目的に，ステアリング走行振動を位相差解析した．タイヤ回転次数振動のサイドバンドがキャリアと180°の位相結合を持ち，振幅変調のFFT表現であることを発見した．本知見に基づくパラメトリック加振モデルにより，従来手法に対する信号再現性の向上を示した． Translation
Abstract(E)	To reproduce road feel in steer-by-wire vehicles, phase difference analysis was applied to steering vibration during driving. The sidebands of tire rotational order vibration were found to be phase-coupled to the carrier at 180°, indicating they represent amplitude modulation in the FFT domain. A parametric excitation model preserving this coupling structure was proposed, demonstrating improved signal reproducibility compared to conventional methods.

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".
