Abstract(J)プロペラシャフト方式AWDの路面入力に対するピッチ振動について,5自由度(Z, q, X, w1, w2) モデルを用いた解析を実施.前輪と後輪のサスペンション軌跡の差により,内部循環トルクに起因するピッチ減衰モーメントが発生.先述の効果により,AWD車は2WD車に対しピッチ振動が減少することを計算,実験の両面から検証した.

Translation

Abstract(E)Analysis of pitch motion in propeller shaft AWD systems in response to road input was conducted using a 5-DOF (Z, q, X, w1, w2) model. Differences in the suspension trajectories of the front and rear wheels generate pitch damping moments due to internal torques. The aforementioned effect was verified both computationally and experimentally, showing that pitch motion is reduced in AWD vehicles compared to 2WD vehicles.

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.
