Abstract(J)本稿では、エネルギー伝達特性を用いた単性能事例の一つとして、二自由度振動系間のエネルギー伝達特性を用いて、エンジンシェイクの既存の低減方法をエネルギー伝達の観点から解釈する。特に、エンジンシェイクの代表的な低減手法であるエンジンバウンシングとピッチングを連動させる方法や、液封マウントによる方法に焦点を当てる。これらの検討を通じて、エネルギー伝達特性の制御に基づく振動低減策が、解析の精度向上と設計の見通しのよさにおいて非常に有用であることを示す。

Abstract(E)This paper introduces an approach using energy transmissibility to analyze the average vibration response of a 2-DOF system. It demonstrates how this method simplifies predictions for a 2-DOF vibration system consisting of two masses and springs. Additionally, it reviews previous studies on engine shake reduction, which involve strategies considering the coupling of bouncing and pitching motions, and the use of hydraulic engine mounts as dynamic dampers. These strategies are then related to energy transmissibility. In conclusion, this paper highlights the utility of energy transmissibility in understanding vibration phenomena, designing vibration responses, and fostering innovative ideas for vibration reduction.

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".
