Abstract(J)ロードノイズはランダムな路面凹凸を加振源とする現象である。そのため、CAEへ適用した際にメカニズム分析が困難になる。本報では路面入力を確定的な位相を持つタイヤ接地面での単純な入力パターンに置換することで、周波数軸ベースの分析技術が適用可能となり、効率的にメカニズム分析ができることを示す。

Abstract(E)Road noise is a phenomenon caused when tires go through on random road surface asperities. Therefore, it is difficult to perform root cause analysis using mode contribution analysis etc. because such analysis needs to use excitation forces with definite phases. In this paper, it is shown that root cause analysis for road noise based on frequency domain-based techniques can be performed efficiently by replacing the random road excitation with a simple input pattern at the tire contact patch.

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".
