摘要轨道不平顺是诱发车-桥系统耦合振动的主要激励源之一，探明系统耦合振动不平顺敏感波长，对线路管理具有重要参考价值。首先，建立了高速磁浮列车-轨道梁耦合系统空间模型，其中磁浮列车被模拟为具有537个自由度的多体动力学模型，轨道梁被模拟为空间有限元模型，两者之间通过基于PD控制理论的磁轨关系耦合。其次，以上海高速磁浮为研究背景，选用5车编组列车驶过20跨简支梁桥为计算条件，通过与实测结果对比验证了模型的正确性。最后，考虑轨道谐波不平顺激励，探讨了不同方向的轨道不平顺组合、不同轨道不平顺幅值和不同车速对列车和桥梁动力响应敏感波长及列车运行平稳性的影响。结果表明：磁浮车-桥系统横向振动和竖向振动耦合性很弱；在设计车速430 km/h下，车体竖向、侧滚和点头加速度敏感波长分别为140~180 m、60~100 m和120~160 m，车体横向和摇头加速度敏感波长大于200 m；波长为80 m、105 m、115 m、140 m和160 m时会分别引发车体侧滚、摇头、横向、点头和竖向方向的共振；车体和主梁的响应幅值与轨道不平顺幅值基本呈线性关系；当轨道不平顺幅值为1mm时,在计算车速200、250、300、350、390和430km/h工况下车体侧滚加速度峰值随车速变化不大，其他四个自由度方向的加速度峰值随着车速的增大而减小，主梁竖向加速度幅值随车速的增大成呈线性增大；从车体的横向和竖向Sperling指标可以看出，车体的Sperling指标均小于2.5，磁浮车辆的运行平稳性良好。

Abstract：Track unevenness is one of the primary sources of excitation that induces coupling vibrations in the vehicle-bridge system. The sensitive wavelength of the coupling vibration in the system has been identified, which holds significant reference value for line management. Firstly, a spatial model of the high-speed maglev train-track beam coupled system is established. In this model, the maglev train is simulated as a multibody dynamic model with 537 degrees of freedom, while the track beam is simulated as a spatial finite element model. The two are coupled through the magnetic track relationship based on PD control theory. Secondly, the Shanghai high-speed maglev is used as the research background, and a 5-car marshalling train crossing a 20-span simply supported girder bridge is selected as the calculation condition to verify the correctness of the model by comparing it with the measured results. Finally, considering the uneven excitation of track harmonics, the effects of different combinations of track unevenness in various directions, different amplitudes of track unevenness, and different vehicle speeds on the sensitive wavelength of dynamic response and ride stability of trains and bridges are discussed. The results indicate that the coupling of lateral and vertical vibrations in the maglev-bridge system is weak. At a design speed of 430 km/h, the sensitive wavelengths of the car body in vertical, roll, and pitch accelerations are 140-180 m, 60-100 m, and 120-160 m, respectively. The sensitive wavelengths of the car body in lateral and yaw accelerations are greater than 200 m. Resonance in the body roll, yaw, lateral, pitch, and vertical directions can be triggered at wavelengths of 80 m, 105 m, 115 m, 140 m, and 160 m, respectively. The response amplitudes of the car body and main beam are generally linearly related to the amplitude of track unevenness. When the amplitude of track unevenness is 1 mm, the peak roll acceleration of the car body does not change significantly with vehicle speed, while the peak accelerations in the other four degrees of freedom decrease with increasing vehicle speed. The vertical acceleration amplitude of the main beam increases linearly with vehicle speed. The lateral and vertical Sperling indicators of the car body indicate that the Sperling index of the car body is less than 2.5, indicating good ride stability for the maglev vehicle.
