Abstract(J)二輪車のフレーム剛性は,直進の安定性に影響を与る. 従来,これらの影響は、複数のフレーム剛性が組み合わされた数学モデルを使用して分析されてきた. 本論文では複合フレーム剛性モデルから直進安定性に対する単一フレーム剛性の影響を分析するための方法を提案する. 具体的には、個々のフレームの剛性の影響は,疑似10自由度モデルを使用して推定できることを述べる.すべてのフレーム剛性値が非常に大きくした際に,その固有値が4自由度モデルのものと同じになるモデルを疑似10自由度モデルとする.

Abstract(E)Motorcycle frame flexibilities affect the straight running stability. Conventionally, the effects of these have been analyzed using a mathematical model in which multiple frame flexibilities are combined. In this paper, it is proposed that a method for analyzing the effect of a single frame flexibility on straight running stability from a composite frame flexibility model. Specifically, it is described that the influence of individual frame flexibility can be estimated using a pseudo 10 degree of freedom model. In the pseudo 10 degree of freedom model, the eigenvalues are the same as the eigenvalues in the 4 degree of freedom model when all frame stiffness values are extremely large.

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.
