摘　　要：以东风_4型内燃机车为例,用简化了的内燃机车车体结构,建立了定置状态下3种输入情况的内燃机车的统计能量分析(SEA)模型,得出了与机车在负荷试验台上进行试验时相符的模型,给出了机车各主要牵引噪声源对环境的噪声贡献量的计算方法,并实验验证了理论分析的结论。The three kinds of models of deisel locomotive DF4, which are based on statistical energy analysis (sea), are built and one of them is built according to the condition of locomotive load cell test stands. The aim is that the calculation method is given on noise contribution of the main noise sources to environment. On the other hand, it is proved that the test agrees well with the theoretical analysis.
