Abstract: In this paper, the statistical energy analysis (SEA) is applied to prediction of the noises of high speed railway bridges. Based on analysis on the relationship between the principle of SEA and production of noises of high speed railwaybridges, SEA is considered as a feasible method for predictingnoise radiation of high speed railway bridges. Amathematical model of energy exchange among the sub-structures of railway bridges is proposed by using SEA.
