Abstract(J)ねじり振動の減衰機構はエンジンルーム内レイアウトの制約を大きく受けるため、開発初期に必要な減衰性能を精度よく予測する必要がある。しかしながらエンジントルク変動予測が企画段階では精度が低く手戻りの原因となっているため、実機がない段階でトルク変動を統計的手法により精度よく予測する技術を構築した。

Abstract(E)The accurate prediction for damping performance is required in early stage of development because damping device such as flywheel, is strictly restricted in space of engine room. However, the accuracy of estimation of engine torque fluctuation is low and this causes redesign the concept of vehicle. In order to solve this problem, we constructed technology using statistical method that enable to predict high accuracy within 5 % of engine torque fluctuation without having actual engine. This paper introduces this new method.

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.
