| Abstract: | Based on the hybrid finite element and statistical energy analysis(hybrid FE-SEA) and the principle of periodic substructure,a acoustic characteristic simulation model of external corrugated floor used in high-speed train was established.According to the transmission loss of external corrugated floor structure,the sound insulation property was evaluated.Corrugated floor structure,corrugated floor structure with top plate,corrugated floor structure with bottom plate,corrugated floor structure with splint wer... |
