Abstract(J)以前,筆者らは,エンジン燃焼騒音の音質を改善するための構造系伝達特性の中間評価指標を開発した.しかし,この指標は筒内圧を参照信号とした周波数応答関数を基にしているため,実稼働試験が不可欠であった.そこで,静止したパワープラントに対して加振実験を行うことにより,実稼働試験レスで類似の指標を得る方法を開発した.

Abstract(E)The authors previously developed an intermediate evaluation index for transfer characteristics of the structural system of the completed vehicle to enhance the sound quality of combustion noise. Based on the results, a method was developed to obtain an index for the power unit similar to the above intermediate evaluation index by a shaker test on a stationary power plant. It was found that this shaker test and transfer characteristics evaluation method can approximately estimate the frequency band in which the structural system amplifies half-order components of the combustion noise related to sound-quality deterioration without conducting an actual engine operation test.

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.
