降低铁道车辆车内噪声的研究

Research on Reducing Interior Noise of Rolling Stock

以来自转向架的固体传播噪声为中心,对噪声传播特性进行了分析,提出了一种降低固体传播噪声的新方法,即采用悬挂地板结构,并运用试验车辆进行了验证。

With solid-borne noise of the bogie as the focus, the features of noise transmission are analyzed.A new method to reduce solid-borne noise, i. e., applying the suspended floor structure, is given, and verified by the testing vehicles.
