摘要
对客货列车运行稳态辐射噪声的传播特性进行了试验研究。通过分析列车运行试验数据 ,得出列车运行噪声在一般传播条件下几何衰减特性及噪声强度与运行速度的定量关系方程。
The transmission characteristics of the steady state radiation noise in operation of passenger and freight trains are tested and researched.Through analysis of test data in operation of trains,the quantitative relation equation between the running speed and the geometric attenuation characteristics under normal transmission conditions,the noise intensity in operation of the train is obtained.
