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-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。
In recent years, along with the speeding up of China’s railway trains, the construction of express passenger lanes, the development of high-speed railways and urban rail transit, wheel-rail noise has begun to attract domestic attention. According to the theory of vehicle-track coupling dynamics and sound radiation and propagation theory, the mechanism of wheel-rail noise generated during train operation is analyzed. On this basis, the basic law of the wheel-rail noise radiation is analyzed.
