为研究轨道交通车辆悬挂系统参数不确定性对车辆振动及乘坐舒适度的影响，构建了一个综合考虑悬挂参数不确定性的转向架-车体-座椅耦合系统垂向动力学模型，对高速列车转向架-车体-座椅垂向耦合振动系统开展车辆振动响应分析、运行平稳性分析和灵敏度分析。研究结果表明：悬挂参数的不确定性不仅会显著改变车辆的垂向随机振动特性，还直接影响其运行平稳性；不同频率范围内车辆垂向振动响应对悬挂参数的敏感度存在显著差异，因此设计优化悬挂参数时需根据频率特性进行有针对性的调整。研究结果将为高速列车转向架-车体-座椅垂向耦合系统的动力学分析及优化设计提供参考。
Abstract：The vibration of rail transit vehicles has always been the focus of researchers, and due to environmental changes and manufacturing errors, vehicle suspension system parameters have significant uncertainties, which often affect vehicle vibration and ride comfort. In this paper, a vertical dynamics model of bogy-body-seat coupling system considering the uncertainty of suspension parameters is constructed. Based on this model, the vehicle vibration response analysis, running stability analysis and sensitivity analysis are carried out for the vertical coupling vibration system of bogy-body-seat of high-speed train. The results show that the uncertainty of suspension parameters not only significantly changes the vertical random vibration of the vehicle, but also directly affects its running stability. The sensitivity of vehicle vertical vibration response to suspension parameters in different frequency ranges is significantly different, which means that targeted adjustments should be made according to frequency characteristics during design optimization. The research results will provide a reference for the dynamic analysis and optimization design of the vertical coupling system of bogies, car bodies and seats in high-speed trains.
