| Abstract(J) | 近年，自動車のNV性能向上と軽量化という相反する要求が高まっている．筆者らはこれまで，ハイブリッドSEA法を用いた防音材構成や適用位置の最適化を検討することで，この問題を解決してきた．本論では，まず電気自動車に本手法を適用し手法の有効性を示す．さらに車体軽量化とNV性能向上提案に対する検証も行った． Translation |
| Abstract(E) | Hybrid SEA modeling method has been used to study the soundproof of a gasoline vehicle. In recent years, an electric vehicle is center of attention from the viewpoint of environmental performance; noise-vibration measures are required. Therefore, we compared the noise insulation index of an electric vehicle and a gasoline vehicle and examined soundproof performance of an electric vehicle. In this paper, at first, we compare the noise insulation index of an electric vehicle and a gasoline vehicle. Next, we make the Hybrid SEA model of an electric vehicle for consideration of noise insulation performance. And we verified the accuracy of the Hybrid SEA model. We compare the energy ratio and the damping loss factor by using the Hybrid SEA models of an electric vehicle and a gasoline vehicle. And we consider those results and show soundproof performance of an electric vehicle. |
