摘要/Abstract

摘要： 为实现列车低噪声设计，给乘客营造良好的乘车环境，需要对列车车内噪声贡献来源进行探究，而目前对于各个速度下高速列车车内噪声贡献来源的研究还不够全面，全面分析列车车内噪声贡献来源对于实现高速列车噪声与振动控制具有重大意义。基于工况传递路径分析（Operational transfer path analysis，OTPA）方法，以带有受电弓的拖车端部（转向架上方）客室内距离地板1.2 m处噪声作为目标响应点，建立列车客室内噪声的传递路径分析模型，详细分析车内噪声的传递路径贡献量以及声源贡献量。结果表明，列车低速运行时转向架区域贡献占主导地位，当高速列车速度高于300 km/h时主要贡献位置变为受电弓与顶板区域。车外噪声激励以结构传声的形式传播为主，空气传声对车内噪声影响不大。牵引拉杆振动在160～315 Hz的1/3倍频程频带内贡献量较大，受电弓区域振动在250 Hz的1/3倍频程频带处贡献量最大，抗侧滚扭杆振动在630 Hz的1/3倍频程频带处是主要贡献量。研究结果可为轨道交通车辆噪声与振动控制措施提供指导方向。

Abstract: In order to realize the low noise design of the train and create a great riding environment for the passengers, it is necessary to explore the source of noise contribution inside the train. And the current research on the source of interior noise contribution to high-speed train at various speeds is not comprehensive enough. A comprehensive analysis of the source of noise contribution is of great significance for realizing high-speed train noise and vibration control. Based on the operational transfer path analysis(OTPA) method, taking the interior noise of the point that has 1.2 m from the floor above the bogie and under the pantograph as the target point, an OTPA model of high-speed train is developed. The contribution of transfer paths and sources to interior noise are analysed in detail. The results show that the floor contribution and bogie contribution are dominant at low speeds. After the speed exceeds 300 km/h, the contribution of the roof and pantograph contributions are dominant. The noise source outside the vehicle is mainly transferred into the car through the structure-borne noise, and the contribution from air-borne noise is small. In 160-315 Hz, the contribution of the vibration of the traction rod connecting area is the most significant. In 250 Hz, the contribution of vibration of the pantograph base is the most significant. In 630 Hz, the vibration of anti-roll torsion bar is the major contribution. The research results can provide guidance for the noise and vibration control measures of rail vehicles.
