The invention provides a method for reducing carriage noise, a damper, a noise reduction structure and a rail vehicle, and can be applied to the technical field of noise reduction and the technical field of rail transit. The method comprises the steps that noise time domain signals of multiple test points of a target rail vehicle in the running period are obtained, and the multiple test points comprise the test points of the vehicle end of the target rail vehicle and the test points in a carriage of the target rail vehicle; analyzing the noise time domain signals of the plurality of test points, and determining a target test point and a plurality of first candidate areas corresponding to the target test point; based on the simulation model, sending noise time domain signals corresponding to the target test point to the plurality of first candidate areas by simulating a target noise source to obtain first vibration response information of the plurality of first candidate areas; determining a target area from the plurality of first candidate areas according to the first vibration response information; and installing a damper in the target area.

    本公开提供了一种用于降低车厢噪声的方法、阻尼器、降噪结构及轨道车辆,可以应用于降噪技术领域和轨道交通技术领域。该方法包括:获取目标轨道车辆在运行期间多个测试点的噪声时域信号,其中,多个测试点包括目标轨道车辆的车端部的测试点和目标轨道车辆的车厢内部的测试点;对多个测试点的噪声时域信号进行分析,确定目标测试点和与目标测试点对应的多个第一候选区域;基于仿真模型,通过模拟目标噪声源向多个第一候选区域发送与目标测试点对应的噪声时域信号,得到多个第一候选区域的第一振动响应信息;根据第一振动响应信息,从多个第一候选区域中确定目标区域;以及在目标区域安装阻尼器。
