| Abstract(J) | 車外騒音及び車内音の双方を解析できるHSEAモデルを構築した。そのモデルを用いて防音材の最適化を行った結果、車外及び車内のNV性能を約1dB改善しつつ、0.77kgの軽量化を実現した。また、実験のみの開発期間と比べ80%の時間削減に貢献した。 Translation |
| Abstract(E) | We have developed HSEA model that can analyze both exterior and interior noise. As a result of optimizing the soundproofing material using that model, the NV performance exterior and interior the vehicle was improved by about 1 dB and the weight was reduced by 0.77 kg. In addition, the experimental development period was reduced by 80%. |
