列车运行噪声频率特性及等效频率试验研究

摘要

The test and research are made on the frequency features of thestable radiation noise in operation of passenger and freight trains.Through analysis of the train operation test data，the distribution features of the radiation noise frequency and the equivalent frequency values under different speeds in operation of the train are obtained.%对客货列车运行稳态辐射噪声的频率特性进行了试验研究，通过分析列车运行试验数据，得出列车运行辐射噪声频率分布特性及不同速度下的等效频率值。
