概要
Artificial intelligence and machine learning (AI/ML) models are revolutionizing how mathematical models of engineered systems are built and enhanced. When combined with physics-based simulations they increase in their predictive power and can be harnessed for enhancing innovation and productivity. In this talk we will discuss how physics simulations enhanced by AI/ML can 1. How Ansys SimAI will accelerate innovation by generating solutions for novel geometric designs 2. Accelerate insights derived from simulations by enabling high-fidelity design space exploration. 3. Reduce physical testing by adding the effect of residual physics in physics models 4. Discover the value of historical data by making them relevant for current generation design. By frontloading simulations enhanced AI/ML models in the engineering design process engineers can achieve higher productivity and accelerated product development. In this talk we will discuss how to achieve this with use-cases from the automotive industry.
歩行者 vs 自動車の交通死亡事故の損傷部位は、頭部が最も高い割合を占めており重要な課題となっている。今回、バーチャル人体モデルTHUMSを用い、衝突方向と頭部傷害値との関係をシミュレーションより明らかにした。また、頭部がエンジンフードに衝突する際の挙動と、最大脳ひずみの発生メカニズムについて調査した。
The presentation will demonstrate a cabin heat-up and cool-down scenario utilizing a novel TAITherm based coupling methodology for cabin thermal simulation, discussing the proposed solution’s accuracy and efficacy. 車室内快適性能の向上のために、車両開発においては効率よくキャビン温熱解析を実施するニーズが高まっています。本講演では、ThermoAnalytics社のTAIThermと他社市販のシステムツールの連成による新しい効率的な解析手法をキャビン温熱解析に適用した事例を紹介します。本事例を通して、計算速度、精度を満たすシミュレーションの実用性を報告します。
