摘要

针对高速动车组提速后车辆横向振动加剧、乘坐舒适性下降的问题，本文以 CRH2C 动车组为研究对象，在 VI-Rail 环境中建立车辆动力学模型，并与 MATLAB/Simulink 进行联合仿真，提出一种基于 Skyhook 与 Groundhook 的半主动悬挂混合控制策略，以权重因子

调节两种控制策略的作用权重。针对德国标准线性低不平顺谱轨道、列车以 70 m/s（252 km/h）运行的工况，以车体横向加速度峰值与均方根值为评价指标，对比混合控制与被动控制的效果。结果表明：当

取 0.9~1.0 时，混合控制抑制横向振动的效果优于被动控制，车体横向加速度均方根值最大降低约5.1%；当

趋近于 0（趋于纯 Groundhook 控制）时反而不及被动控制。该策略可在不改变车辆结构的前提下改善高速动车组乘坐舒适性，工程应用中权重因子宜取 0.9~1.0。

Abstract

The increasing operating speed of high-speed electric multiple units (EMUs) intensifies the lateral vibration of the vehicle and degrades the riding comfort. Taking the CRH2C EMU as the research object

this paper establishes a vehicle dynamics model in VI-Rail and conducts a co-simulation with MATLAB/Simulink. A semi-active suspension hybrid control strategy based on the Skyhook and Groundhook strategies is proposed

in which the weighting factor

regulates the relative contribution of the two strategies. For a train running at 70 m/s (252 km/h) on a track characterised by the standard German linear low irregularity spectrum

the peak value and the root mean square (RMS) va

lue of the lateral acceleration of the car body are used as evaluation indices to compare the hybrid control with the passive control. The results show that when

falls within the range of 0.9-1.0

the hybrid control suppresses the lateral vibration more effectively than the passive control

reducing the RMS values of the lateral acceleration of the car body by up to approximately 5.1%; when

approaches 0

that is

when the control degenerates into the pure Groundhook strategy

the performance is inferior to that of the passive control. The proposed strategy improves the riding comfort of high-speed EMUs without modifying the vehicle structure

and a weighting factor in the range of 0.9-1.0 is recommended for engineering application.
