Abstract(J)モデルベースの車両開発で利用される要素特性テーブルの作成時間を短縮するために、ある条件で作成した要素特性テーブルの値を正規直交分解して求められる基底を使って、別の条件の要素特性テーブルを予測する方法を提案する。提案方法をモータ損失マップの作成に適用し、有効性を検討した結果を報告する。

Translation

Abstract(E)This study proposes an efficient method for generating an element loss table, which is used to simulate a full vehicle system in a model-based design. To reduce the computation time required for the loss table generation, the data on some selected points in the loss table is decomposed into orthogonal bases. The bases are utilized to estimate the data on the other points. The efficiency of the proposed method in terms of the estimation error as well as the calculation time is discussed through the generation of a motor loss map.

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.
