Abstract(J)	500Hz以下の低周波空力騒音の車内への伝達メカニズムを解析するため、簡易形状箱モデルを対象としたCFDとFEM解析による解析精度の検証を行った。車内へ伝達される低周波の主要な空力騒音は空力加振と音響加振およびパネル共振により放射される。 Translation
Abstract(E)	A combined CFD and FEM simulation of a simplified box model was conducted to investigate a transmission mechanism of a low-frequency wind noise which is up to 500Hz. The low-frequency wind noise is mainly transmitted by resonant vibrations due to the hydrodynamic and acoustic input.

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
