| 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 railway bridges, SEA is considered as a feasible method for predicting noise radiation of high speed railway bridges. A mathematical model of energy exchange among the sub-structures of railway bridges is proposed by using SEA. |
