    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 were chosen, and the sound insulation properties of the structures were analyzed under different web angles. Calculation result shows that the sound insulation losses of corrugated floor structure and corrugated floor structure with top plate are bigger than the other two structures at every angle. Corrugated floor structure with bottom plate has the worst sound insulation property, but corrugated floor structure with top plate has the best sound insulation property, and their sound insulation difference is 6.9 dB while the web angle is 55°. Through the analysis of sound insulation loss, the best combinations of external corrugated structures and web angles under different frequency noises are obtained, which can provide evidence for the low-nosie structure design of external corrugated floor for high-speed strain.
