| Abstract(J) | ベアリングの摩擦損失は電気自動車の駆動系のエネルギー損失で無視できない比率を占める．摩擦損失を低減すればライフサイクルにおけるCO₂排出（下流）が減少するだけでなく，必要なバッテリー容量を抑制でき製造段階のCO₂排出（上流）とコスト削減にもつながる．本報告ではベアリングを対象に，ダウンサイジング，設計最適化，ドラグ損失最小化の手法を適用し動力損失低減の効果を示す． Translation |
| Abstract(E) | Bearing losses add up to a significant share of overall vehicle power losses. On the one side, this influences the downstream emissions, on the other side a BEV's upstream emissions are heavily affected well as a certain capacity of the battery is only needed to feed these losses. Every piece of energy which is not lost to friction doesn't have to be stored in a battery. This lecture discloses the hidden potentials in mechanical power loss reduction, especially for bearings, by means of power density increase, on-the-point optimization and drag loss minimization. |
