摘要
通过测取干线上货车正常行驶状态下稳态辐射噪声的等效声级和货车运行速度的现场数据，研究了货车轮轨噪声与传播距离的定量关系，得出符合我国干线货车运行噪声传播规律的方程。
Through measurement of the equivalent sound level of the steady state radiation noise and the field data of running speed under normal running conditions of freight cars on main lines,the quantitative relation between freight car wheel rail noise and the propagation distance is studied,the equation conformable to the propagation law of running noise for freight cars on main lines in our country is obtained.
