中文摘要：

近年来，随着我国铁路列车提速、快速客运专线的建设、高速铁路以及城市轨道交通的发展，轮轨噪声在国内开始受到关注。根据车辆一轨道耦合动力学理论及声辐射与传播理论，分析了列车运行过程中产生轮轨噪声的机理。在此基础上，分析了轮轨噪声辐射的基本规律。

英文摘要：

In recent years, with the raising of train speed, the construction of the fast passenger line, and the development of high-speed railway and mass rail transit, wheel/rail noise is paid attention greatly in China. On the basis of the theory of vehicle-track coupling dynamics and noise radiation and propagation, mechanism of wheel/rail noise is analyzed. Further more, the basic rule of wheel/rail noise is presented.
