摘　　要：对高速列车轮轨噪声产生机理进行了理论分析，论证了钢轨振动产生的辐射噪声是轮轨噪声的主要成分；通过对模拟运行的高速列车轮轨噪声源的测试与分析，表明列车运行速度是影响轮轨噪声大小的主要因素之一，由此提出高速列车轮轨噪声控制的有效方法。The wheel/rail noise generated by high speed trains are theoretically analyzed. It is shown that the radiative noises generated by vibrations of the rails are the main sources of wheel/rail noises. It is also revealed, through a simulation of high speed train and measurement of the source of noises, that the speed of a train is one of the main factors affecting wheel/rail noises.Some measures to control the noises are suggested.
