Abstract(J)電着塗膜析出に関する数理モデルを構築し、複数の塗料を用いた実験とシミュレーションの比較により妥当性を検証した。このモデルを、4節点四面体要素でも高精度な計算が可能な次世代有限要素法(ES-FEM)のコードに実装し、実ラインおよび実車形状を用いた大規模な解析でも塗料特性の差を表現できることを実証した。

Abstract(E)We developed a numerical electrodeposition (ED) model and validated its accuracy by comparing experiments and simulations using various kinds of paints and pretreated steel plates. The model was implemented in a next-generation finite element code (ES-FEM), which achieves high accuracy even with 4-node tetrahedral meshes. Besides, it was demonstrated that the difference in paint and pretreatment properties can be simulated adequately in large-scale analysis using actual paint process and car body models.

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.
