摘要
以列车在高架桥上运行的工况为例,简化高架结构,建立了统计能量分析(SEA)模型,利用统计能量分析软件对列车通过高架桥时的振动噪声进行了计算分析。理论分析结果表明采用该种方法分析列车通过高架结构时辐射的噪声是可行的。
Based on statistic energy analysis （ SEA ） , SEA model was built when train was running on viaduct. This model was calculated by SEA software. The calculation results showed that it is feasible to analyze noise of train running on viaduct based on SEA.
