摘要：
轨道不平顺激扰是影响高速列车横向振动最常见和最主要的因素，而目前对不同频率轨道激励下车辆横向振动以及其半主动悬挂控制算法实现的研究甚少。基于此，建立高速列车17自由度车辆横向振动仿真模型，运用经验模态分解基于频域采样的三角级数法模拟的轨道谱信号，并重构得到不同频率的轨道激励，对不同频率轨道激励下车辆横向振动和横向半主动悬挂天棚阻尼控制算法进行研究。研究结果表明，影响车辆横向振动的轨道谱信号主要集中在0~10 Hz；在270 km/h的运行速度下，当天棚阻尼控制算法的比例系数k取7.5~8.5时，车辆横向平稳性得到较大改善，可为轨道谱优化与改进以及天棚阻尼控制算法实现提供理论指导。

Abstract: Track irregularity is the most common and important factor affecting the lateral vibration of the high-speed trains. At present, vehicle lateral vibration and semi-active suspension control algorithm under different frequency track excitations are rarely researched. Based on this, a simulation based on a 17-degree-freedom vehicle lateral vibration model is done, using EMD to decompose the track spectrum signals simulated by the trigonometric series method based on frequency domain sampling, and reconstructed to obtain track excitation at different frequencies. Under different frequency track excitations vehicle lateral vibration and lateral semi-active suspension skyhook damper control algorithm are studied. The results show that track spectrum signal influenced vehicle lateral vibration mainly concentrates in 0-10 Hz; at the speed of 270 km/h, when the proportional coefficient k about skyhook control algorithm is between 7.5-8.5, the vehicle lateral stability is greatly improved, which can provide theoretical guidance for the optimization and improvement of track spectrum and realization about skyhook control algorithm.
