    Abstract
  • According to noise barrier design scheme of special railways for passenger transportation from Beijing to Tianjin, the finite element model of noise barrier was established based on the general software ANSYS. The natural frequency of noise barrier structure was detailedly researched and a practical calculation model was presented. The dynamic environment around the noise barrier,which includes the natural wind pressure and the air turbulent force induced by the high speed train, was considered to simulate the transient dynamic response of the noise barrier structure. The laws of each component-s vibration of the noise barrier structure were obtained. In addition, items needed be paid attention to was put forward.
