Abstract(E)This study proposes a low computational-cost design method for ride comfort. The point of the proposed method is to replace the computationally expensive multibody dynamic calculation with the computationally reasonable eigenvalue analysis. To establish the method, we focused on the analogy of the eigenmodes with the features extracted by PARAFAC decomposition from the obtained results with the multibody dynamic calculation. As a result, it is found that the method enables the qualitative changes in the evaluation index during optimization. The proposed method has potential to reduce time for the design study of running performance including ride comfort.

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.
