					<description><![CDATA[Ansys Workbenchによるトポロジー最適化解析。

<p>電車内で荷物を載せる網棚は、下の写真のような部品（ハンガー）で壁面で固定支持されています。<br>電車がより多くの人や荷物を運ぶためには、ハンガーのような個々の部品も含めて車両の軽量化が大変重要です。<br>耐荷重性能を満たしつつ贅肉をそぎ落としたハンガーの形状を、トポロジー最適化で求めた事例です。</p>

<h4 class="wp-block-heading">トポロジー最適化（Topology Optimization）</h4>



<p>トポロジー最適化とは、荷重など決められた設計条件下で、制約条件（例えば質量・応力・部材サイズなど）満たした上で、要求する性能（例えば軽量化）を最大限得られる構造・形状を求める方法です。</p>



<p>孔を空けるなど形態を変更できるため自由度が高いという特徴があります。<br>対象パターン、抜き方向、抜き勾配、空洞回避などの製造制約も設定できます。</p>

<h4 class="wp-block-heading">レベルセット法</h4>



<p>レベルセット法では領域の輪郭の曲線状態（収縮、膨張、曲率変化等）を偏微分方程式により表し、状態変化させながら必要な領域を判定する方法です。<br>曲線を変化させながら解くため滑らかな形状を保つことができます。</p>

<div class="wp-block-column is-layout-flow wp-block-column-is-layout-flow" style="flex-basis:66.66%">
<p>構造物が破壊する際には、材料や荷重条件などによっていくつかの破壊形態があります。<br>鉄筋コンクリートは鉄筋とコンクリートを組み合わせた構造で、それぞれの特徴を生かした構造部材として一般的に使われます。<br>コンクリートは大きな圧縮荷重を負担することができますが、塑性変形をほとんど伴わない脆性破壊をする材料の代表例です。一方、鉄筋は引張や曲げ荷重に強く、破断する時は金属の代表的な破壊形態である延性破壊となります。</p>



<p>LS-DYNAでは、破壊基準を満たした要素を削除することで破壊を表現できます。ひずみや応力等の複数の破壊基準の中からどの基準を使うかは、ユーザーがモデルの破壊形態を理解して選択する必要があります。</p>

<h4 class="wp-block-heading">粒子法（SPH法）</h4>



<p>Smoothed Particle Hydrodynamics 法 (SPH法)は<a href="https://ja.wikipedia.org/wiki/%E6%95%B0%E5%80%A4%E6%B5%81%E4%BD%93%E5%8A%9B%E5%AD%A6">流体力学</a>や材料力学にて用いられる微分方程式の<a href="https://ja.wikipedia.org/wiki/%E6%95%B0%E5%80%A4%E8%A7%A3%E6%9E%90">数値解析手法</a>の一つで、粒子法の一種です。粒子法は対象となる連続体を有限個の粒子の集団に置き換え、ナビエ・ストークス方程式などの連続体の支配方程式を元に導かれる粒子間相互作用に従って粒子を移動させる手法です。</p>



<p>SPH法は物体が破断したり小さな破片や飛沫が飛び散ったりするような現象も自然に計算可能であるため、流体の飛散や航空機エンジンのバードストライクなどの解析に使用されています。</p>
