| Abstract: | As to the issues that the strong acoustic pressure which is generated on structure surface by running high speed train would lead to a series of problems such as deterioration of ride environment and structure damage,a finite element model of acoustic-vibration coupling is established for a high speed train to study the structure modes of carriages,interior acoustic field modes and structure-acoustic coupling system modes;for the special dynamic environment,the harmonic response of coupling system is calcul... |
