| Abstract(J) | 電動車の熱管理部品設計において，開発初期に実車環境での最適化を行うことは計算コストの観点から困難である．本研究では，実験式に基づく軽量な1D熱流体モデルを構築し，FMIを介してSimulinkの車両・駆動・空調統合環境へ連携した．パラメータ解析により，3DCFDに依存せず電費や温度挙動に対するロバスト最適仕様を迅速に同定する手法を確立した． Translation |
| Abstract(E) | To optimize EV thermal components early in development, this study proposes a system simulation approach. Lightweight 1D thermal-fluid models based on empirical data are integrated via FMI into a Simulink environment covering the vehicle, drivetrain, and HVAC. Parametric analysis of thermal resistance and capacity demonstrated that this method rapidly identifies robust, optimal component specifications affecting energy consumption and temperature behavior under various driving conditions, without relying on high-overhead 3D CFD. |
