AI 要約（直近 5 年の研究成果）

大崎研究室は、建築・構造物の設計と形態生成に関する多角的な研究を行っています。一つの大きなテーマは、鋼構造建物の最適設計です。建物の部材寸法や免震装置の配置などを設計変数とし、地震時の応答性能を満たしながら構造コストや鋼材量を最小化する最適化手法を開発しています。この際、局所探索法や強化学習などの計算手法を活用し、実現可能な設計ソリューションを導出しています。もう一つの重要なテーマは、曲面やシェル構造の形態生成です。膜応力の平衡方程式や平均曲率流などの微分幾何学的手法を用いて、製造可能性や構造性能を満たす曲面形状を創成しています。特に展開可能曲面（平面に開くことができる曲面）の設計に力を入れており、建築部材の低コスト製造を実現する形態探索を行っています。さらに、折り紙の幾何学的性質を利用した構造デザインにも取り組んでいます。剛体折り紙の変形メカニズムを解析し、その知見を展開可能な球形ロボットやパネル構造の開発に応用しています。これらの研究を通じて、計算最適化と幾何学的制約の両立による革新的な構造形態の実現を目指しています。
