摘要
介绍了统计能量解析法(SEA)在铁道车辆的车内噪声预测方面的研究成果,阐述了近郊型车辆车内噪声预测中采用的SEA实例,并将其结果与定置试验及运行试验中获得的车辆内外噪声级测定结果进行了比较,显示出SEA的实用性。
The research achievements of statistical energy analysis （SEA） method in prediction of interior noise of railway vehicles are described. The practical SEA examples applied in prediction of interior noise suburban cars are expounded, and the results are compared with the measurement results of noise level inside and outside of vehicle obtained in stationary test and operation test. The practicability of SEA is showed out.
