Abstract(J)コンプレッサ振動伝達音の低騒音化に向け、配管レイアウトに自由度のある設計初期段階でエアコン配管の伝達特性設計を試作レスで実現する必要がある。そこでコンプレッサ振動伝達音に対し、複雑なレイアウトの配管振動を伝達関数合成法にて単品から予測することで、車両システムとしての騒音を予測する技術を確立したので報告する。

Translation

Abstract(E)In order to reduce the noise of the compressor vibration transmission sound, it is necessary to realize the transfer characteristic design of the air conditioning piping without prototyping at the initial stage of design which has a degree of freedom in the piping layout. Therefore, we report on the establishment of a technology to predict compressor vibration transmission sound as a vehicle system by predicting piping vibration of complicated layout by Frequency Based Substructuring.

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.
