Abstract(J)トポロジー最適化は,構造最適化手法の中で高い自由度を有する設計手法である.本報告では,計算パラメータを変えながら,得られる最適形状の複雑さと,目的関数および滑らかさの指標とされる表面積の関係を検討した.その結果,目的関数の値は複雑な形状が,滑らかさは単純な形状が有利となる傾向があることが分かった.

Translation

Abstract(E)Topology optimization provides a high degree of design freedom among structural optimization methods. This study investigates how varying computational parameters affect the relationships between optimal shape complexity, objective function value, and smoothness, represented by surface area. Results indicate that increased structural complexity improves objective function values, while higher smoothness is associated with simpler shapes.

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.
