Abstract(J)非線形解析での歯打ち発生時の衝突力予測モデルと、線形解析での放射音の高周波域までを予測するモデルを組み合わせることで、歯打ち音を設計する手法を構築した。上記により歯打ち衝突力から放射音までを扱う歯打ち音レベルの設計が可能となり、本車両開発に適用した。

Translation

Abstract(E)We constructed the design methodology of rattle noise by using Non-linear simulation model for impact force on the contact face of gears and Linear simulation model for radiation noise with considering high frequency transfer function. This methodology enables to design the level of rattle noise and has been applied to this new vehicle development.

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.
