利用统计能量法软件VA One建立了轨道车辆SEA模型，理论计算了用于SEA分析的各种统计能量参数，最后对车辆内部噪声进行了预测。仿真结果表明：车内噪声主要集中在频率为500~1600 Hz范围内，不同状态下影响车厢内外噪声的主要噪声源会发生变化，噪声峰值出现的位置不同。
利用統計能量法軟件VA One建立瞭軌道車輛SEA模型，理論計算瞭用于SEA分析的各種統計能量參數，最後對車輛內部譟聲進行瞭預測。倣真結果錶明：車內譟聲主要集中在頻率為500~1600 Hz範圍內，不同狀態下影響車廂內外譟聲的主要譟聲源會髮生變化，譟聲峰值齣現的位置不同。

A SEA model of railway vehicle is established by using statistical energy analysis software(VA One), and various parameters for SEA model are calculated theoretically. Finally,the interior noise predictions of the vehicle are achieved. The simulation results show that the vehicle noise mainly distributes in the frequency range of 500~1600 Hz,the main noise sources which influence the interior noise of the vehicle could change under stationary state and operation condition,and the peak values of the noise are in different positions under different states.
