722 ハニカム構造最適化による室内騒音低減に関する研究
詳細
For the vehicle interior noise, muddle sound should be reduced. To reduce the noise, new honeycomb can be used. In this paper, in order to reduce the interior noise by new honeycomb structure, firstly the honeycomb structure is designed and optimized. Secondly frequency response analysis of the interior noise is performed. It is found that the resonant frequency of the indoor air is lowered. Finite element method is used to analyze the interior noise reduction.
