摘要:
车轮辐射噪声是轨道交通噪声的重要贡献源。结合声学仿真和试验技术,分析了某型车轮辐射噪声特性,并设计了一种结合约束阻尼和动力吸振技术的降噪车轮。车轮声学试验结果表明,该车轮降噪方案有良好的降噪效果,车轮声学传递函数幅值降低1~2 个数量级,总声功率级降低11 dB(A) 以上。
Abstract:
The wheel radiation noise is an important contributor of railway noise. Based on the acoustic simulation and experimental techniques, this paper analyzed the radiation noise characteristics of a wheel, and designed a noise reduction wheel combined with constrained damping and vibration absorbing technology. The results of the wheel acoustics test showed that the noise reduction method has a good noise reduction effect. The amplitude of the acoustic transfer function was reduced by one to two orders of magnitude, and the total sound power level was reduced by above 11 dB (A).
