摘　　要：采用有限元法对某新型高速动车组的车体传热系数进行了分区域法计算和整车模型计算,并对两种计算方法的结果进行了比较。结果表明,整车模型计算的K值比分区域法计算的K值大,计算结果更准确。The heat transfer coefficient was calculated by finite element method with compartmentalizing different area and calculating all the hull for the new high speed EMU. The results concluded that the heat transfer coefficient K by calculating all the hull was higher than compartmentalizing area, and even accurately.
